How to control blood pressure in patients with hypertension

It is said that patients with hypertension should pay attention to the control of blood pressure, but how can we effectively control blood pressure? Some patients may think, as long as the medication can control blood pressure, some think that the side effects of drugs, through diet, exercise and other means can also control blood pressure. In fact, the above mentioned are common methods of hypertension control, they are complementary to each other, are indispensable.
Hypertension patients how to control blood pressure?
1 to control blood pressure to regularly measure blood pressure
If there is a family history of patients, be sure to pay attention to regular checks, at home to the volume of blood pressure. In addition, prevention is better than cure and hypertension tend younger, if it is the lifestyle is not the law, often smoking, drinking, obesity high-risk groups should also be regular measurement of blood pressure, once found elevated blood pressure, timely control.
2 control blood pressure to maintain a cheerful mood
Bad psychology is not conducive to the control of blood pressure, easy to cause fluctuations in blood pressure. Therefore, patients with hypertension to everything to open, do not get angry, failing to self decomposition, learn tolerance and understanding, develop an optimistic character, cheerful mood is beneficial to the body health and blood pressure control.
3 adherence to medication is a necessary condition for the control of blood pressure
If you want to control blood pressure, you must adhere to medication. Because high blood pressure is still an irreversible chronic disease, it can only be controlled with antihypertensive drugs. But do not stop after the blood pressure stable without stopping drugs or drugs, it is possible to cause unstable blood pressure, blood pressure once suddenly elevated, it is bound to pose a threat to life. Therefore, adherence to medication is a necessary condition to control blood pressure.
4 low fat and low salt diet to control blood pressure
The principle of diet in patients with high blood pressure is low fat, low salt, low fat, low salt diet to reduce the burden of the heart, but also conducive to the control of blood pressure, so in the diet should pay attention to, as far as possible to eat light food. Of course, light diet is not a vegetarian, to ensure balanced nutrition, to ensure the control of blood pressure at the same time, and will not affect the health.
5 good prevention is the prerequisite for control of blood pressure
Prevention is also a prerequisite for control of blood pressure, young people want to quit drinking, pay attention to their weight, overweight people want to lose weight. At the same time, a reasonable diet, do not eat too heavy for a long time to eat the food, work and rest rules, to take a reasonable way of exercise, strengthen physical exercise. After lifestyle changes, blood pressure is still high, it should be immediately to the hospital for treatment.

Good ways to treat high blood pressure

Good ways to treat high blood pressure

 

Treatment of high blood pressure, in addition to taking another good method
Points: on both sides of sanyinjiao, hanging Bell cave

 

Methods: patients during high pressure high blood pressure, with a smallhealth on both sides of the hammer sanyinjiao; low pressure when high blood pressure is high, with a small hammer hanging Bell point on both sides ofhealth care if a sharp increase in blood pressure, it is immediately in twoblood letting in ear apex.

 

Life, subject to certain advertising misleading, many people think thathypertension is cured, can only rely on blood pressure drugs for life. Then,simply do not want to try some traditional Chinese medicine therapies. They don’t know that, in the view of traditional Chinese medicine, hypertensionis controlled.

 

According to TCM theory, high blood pressure is caused by humans through aircirculation disorders, so just deal with points, by gas back onto the right track of circulation disorders, there are obvious effects.
I, for one, used to treat high blood pressure. One was 98 years old young man, he used to take two or three years of blood pressure medication.Looking for my consultation, I analyzed his symptoms, found what he said wasthe traditional Chinese medicine of liver Qi and using traditional Chinese medicine prescription shengjiang. After he took 3 posts, completely returnto normal blood pressure and condition has not repeated since. Another was amore than 40-year old woman, she has nearly 15 years of a history ofhypertension. I gave her the method is Acupuncture needles, acupunctureevery other day, needle for about two hours at a time, needle twosanyinjiao, for about six months, she would not have anotherantihypertensive drug.

 

Experiences in diagnosis for so many years, I found that there are two waysof treating high blood pressure and high pressure high low high effectiveand high blood pressure.

 

Treatment of hypertension in high pressure and high: knocking on both sidesof sanyinjiao acupoint

 

Stimulating effect of sanyinjiao actually works better than many blood pressure medicine, there are no side effects. In humans, this point is thethree Yin meridians of foot (footjueyin liver channel, foottaiyin spleen,and kidney meridian of footshaoyin) Willow point, which has a greatrelationship with hypertension and liver storing blood, spleen and blood andkidney essence, essence and blood.
Therefore, most suffer from high pressure in patients with hypertension, area common feature, that is, sanyinjiao acupuncture point particularlysensitive, with thumb press, immediately have the feeling of pain orswelling. Rub on time every day as long as you have this feeling there isproof of sanyinjiao effect of lowering blood pressure. But if you did notfeel when pressing, you should be careful, this illustrates your point isslowly failure, so you need to increase the efforts to massage every dayfor more than 10 minutes, let it revitalize it.

 

Treatment of low pressure high blood pressure: percussion on both sidessuspended Bell point

 

Many types of antihypertensive drugs are on the market now, and most of themare high pressure, low pressure drop, easily lead to a series ofcomplications, many friends from the risk of high blood pressure and askedme: is there a safer and more effective drugs, also designed to reducepressure?

 

I tell them: there is! That‘s hanging clock points.

 

Hanging clock points are points on the gall bladder, which specialize incollections of human bone marrow, cord blood, so this points to dredge thechannels and collaterals, Qi and blood of extremely powerful, called thebody naturally decrease the pressure medicine.

 

Sanyinjiao and hanging clock, two baby points you must knock every day, forat least 10 minutes at a time, and beat the time to pay attention, too smallto be not up to the expected results. If the point had no sense of pain,then you should increase accordingly.

 

A sharp increase in blood pressure when

 

Because emotion, fatigue and other reasons, friends suffers from high blood pressure is easy to sharply increase in blood pressure, dizziness, headache,discomfort, which can also lead to cerebrovascular rupture, causinghemiplegia due to stroke, and other serious consequences. Therefore, we musttake urgent measures to pressure when the blood pressure, so as to avoidaccidents.

 

Until the times of high blood pressure has increased dramatically, and thenknock points sanyinjiao and suspended clock is a bit far. In fact, in theexternal treatment of traditional Chinese medicine, there is a mostconvenient, fast, and that two blood letting in ear apex.

 

Tips is the place where human blood is relatively weak, was the place whereblood is very easy to block, as long as the pitchers have to dredge, and canslow down the rapid rise of blood pressure and head pressure.
Friends have high blood pressure, at home preparing some acupuncture withtriangular needle or the hospital uses disposable Lancet, remember inadvance must be to disinfect needles. In urgent cases, no disinfectantaround and above the needle, then use needle on the fire to burn out aswell.

 

After the blood letting in ear apex, blood pressure rises rapidly. Then tapsanyinjiao, or hanging clock points will be able to consolidate the results.

Exercise therapy of hypertension

Exercise therapy of hypertension
Hypertensive disease and rehabilitation Sport Sport type selection to theprinciple of aerobic exercise. To avoid doing in sports push, pull, liftlike the static strength training exercises or breath. Should select those that are systemic, rhythmic, relaxing and easy to comprehensive monitoringof the project. Conditional activities can be used for sports such as track,bike power meter. Hypertensive disease and rehabilitation Sport Sport isconsidered more appropriate kinds and methods of qigong, Tai Chi, medicalgymnastics, walking, jogging, aerobic dance, swimming, recreational sports,outing, fishing and so on. Recommended taking Zhi Tang Tarot reservoirs dropof tea, it is for patients high blood pressure, lower blood pressure.
1, qigong: to relax better, which the discretion of zhanzhuang, strong anddynamic work. Training emphasizes loose, static, down. Required toassist with ideas and simple movements. Idea parts should be lower than theheart, such as Yongquan and pubic region. Breathing should be treated withsmooth breathing, respiratory method should not be used for suspending. Toprolong exhalation to increase excitability of the vagus nerve. Withsubstantial movements should be loose grip, alternating and balanced upperand lower limbs and trunk movement, avoid persistent tensions in prolongedIsometric Contraction movement. Qigong exercises for at least 1 time a day,30-45 minutes at a time. It was reported that after a practice can bringdown systolic blood pressure 2.1~2.4kPa, diastolic blood pressure hasdropped. General practice about two weeks after work. There are reports, agroup of drugs for blood pressure is still not well controlled cases, plusused effective control of blood pressure. In a period of consolidation andused more effectively, often reduce the maintenance dosage 1/3~1/2, andblood pressure remained stable.
2, Tai Chi: because Tai Chi movements soft, muscle relaxation and moresubstantial activities, thoughts and serenity can help lower blood pressure.Practice ends after a set of simplified taijiquan in patients withhypertension, systolic blood pressure can drop 1.3~2.7kPa (10-20mmHg), Tai Chi exercises for a long time the old man resting systolic blood pressureaverages about 2.7kPa less than old people the same age group. To playtaijiquan in hypertensive patients was aware of one of the most importantloose, which caused vascular muscle relaxation reflex relax, prompting adrop in blood pressure. In addition, the Tai Chi with ideas to guide action,highly concentrated, keep quiet, which can help eliminate tension,excitement, nerves in patients with high blood pressure and other symptoms.

 

High blood pressure treatment
Usually as long as the fact that Chicago tea name: Tarot hidden dropadjustment, is a moderate source of compounds of tea polyphenols andcaffeine, can drink, has a good effect on these diseases can avoid theoccurrence of high blood pressure, I hope Members can note this point.Patients with high blood pressure is an important factor in the pathogenesisof obesity, excessive fat in the diet is the decisive factor in fat.

Check items to be done in patients with hypertension

Check items to be done in patients with hypertension
One, to determine whether there is no high blood pressure: the measurement of blood pressure should be continuous several times a few days to measure blood pressure, there are more than two blood pressure rise, it can be described as high blood pressure.
Two, identify the reasons for the high blood pressure: all patients with hypertension, should be asked in detail about the history, a comprehensive system to check, in order to eliminate the symptoms of hypertension.
Laboratory tests can help the diagnosis and classification of essential hypertension, understand the function of target organs, and the correct choice of drugs, hematuria, renal function, uric acid, blood lipids, blood glucose, electrolytes (especially blood potassium), electrocardiogram, chest X-ray and eye bottom examination should be used as routine examination of patients with hypertension.
(a) the blood red blood cells and hemoglobin generally no abnormalities, but hypertension may have negative Coombs test of microangiopathic hemolytic anemia, with abnormal red blood cells, hemoglobin high blood viscosity increased, prone to thrombosis complications (including cerebral infarction) and left ventricular hypertrophy.
(two) urine routine urine routine, renal function impairment, urine specific gravity is gradually decreased, can have a small amount of urine protein, red blood cells, even see tube type, with kidney disease progression, urine protein increased, in benign kidney sclerosis such as 24 hour urine protein in 1g above, suggest poor prognosis, red blood cell and tube type can also increase, tube type is mainly transparent and particles.
(three) renal function by blood urea nitrogen and serum creatinine to estimate renal function in patients with early renal damage check is no exception, to a certain extent can be increased, the adult creatinine >114.3 mu mol/L, the elderly and pregnant women >91.5 mol/L showed renal damage, phenolsulfonphthalein excretion test, urea creatinine clearance rate. The clearance rate could be lower than normal.
(four) the chest X-ray examination showed aortic arch, especially the lift, the lift, tortuous and prolonged, arch or descending part can expand, emergence of hypertensive heart disease with left ventricular enlargement, left heart failure with left ventricular enlargement is more obvious, heart failure or left ventricular and pulmonary congestion increases. Signs of pulmonary edema, pulmonary congestion was obvious, the butterfly shaped fuzzy shadow, routine radiography examination, in order to check before and after comparison.
(five) ECG left ventricular hypertrophy ECG showed left ventricular hypertrophy or a combination of strain, electrocardiogram in diagnosis of left ventricular hypertrophy of the standard is not the same, but its sensitivity and specificity are similar, false negative was 68% ~ 77%, 4% ~ 6% false positive, visible ECG diagnosis of left ventricular hypertrophy sensitivity is not very high. Due to decreased left ventricular diastolic compliance, left atrial diastolic load increases, ECG can appear P is wide, cutting concave, Pv1 terminal force increases, the performance can be found and left ventricular hypertrophy in ECG before, there may be premature ventricular arrhythmias such as atrial fibrillation, etc..
(six) echocardiography and the chest X-ray examination, electrocardiogram, echocardiography in diagnosis of left ventricular hypertrophy is the most sensitive and reliable means, based on two-dimensional ultrasound localization on record M ultrasonic curve or measured directly from the two-dimensional maps, and (or) or ventricular septal wall thickness after ventricular >13mm for left ventricular hypertrophy in essential hypertension left ventricular hypertrophy is symmetrical, but there are about 1/3 in septal hypertrophy (mainly interventricular septum and left ventricular posterior wall thickness ratio >1.3), ventricular septal hypertrophy is often appearing first, suggesting that the first impact of hypertensive left ventricular outflow tract, figure can observe other cardiac chambers echocardiography, valvular and aortic root and can be used for the detection of cardiac function, left ventricular hypertrophy, although the early heart function such as cardiac output, left ventricular ejection fraction is normal, but the left ventricular systolic and diastolic A period of adaptation decline, such as systolic maximum velocity (Vmax) decreased, prolonged isovolumic relaxation, mitral valve opening delay, in the presence of left heart failure after echocardiography can be found in the left ventricular and left atrial enlargement, left ventricular wall contraction weakened.
(seven) fundus examination and measurement of retinal artery pressure can increase, in different stages of the development of the disease can see the following changes in fundus:
Class I: retinal artery spasm
Class II A: mild sclerosis of retina
Class II B: retinal artery was significantly hardened
Grade II: Grade 2 and retinopathy (bleeding or leakage)
Grade IV: Grade III and optic nerve papilla edema
(eight) other examination patients may be associated with serum total cholesterol, triglyceride, low density lipoprotein cholesterol and high density lipoprotein cholesterol lowering, and apolipoprotein A- I decreased, also often have blood glucose increased and hyperuricemia, some patients with plasma renin activity, angiotensin II levels increased.

How to measure blood pressure

How to measure blood pressure
Blood pressure was first in seventeenth Century, a scientist found a glass tube inserted into the horse’s arteries, fortunately, after this design a dangerous and less blood pressure measurement method.
When measuring the blood pressure, the doctor will first be connected to a blood pressure cuff bag slightly tightly wrapped in the forearm to be measured. Then squeeze the attached to the cuff air bag inflated balloon. This temporarily blocks the flow of blood in the aorta (the brachial artery) to the test.
And then the doctor will stethoscopic put in to be measured of the inside of the elbow (placed directly in the artery, the cuff air bag in the air is slowly released. When the blood flow through the artery will hear a beat sound from the stethoscope.
When a doctor hears a sound of first pulses, a reading is recorded on the blood pressure gauge, which is the systolic pressure, and the first reading of the two reading. Systolic blood pressure represents the highest pressure in the arteries. The unit of this reading is a thousand.
With more air gradually from the cuff air bag release, artery will eventually be completely relaxed, intravascular blood flow returned to normal. The pulsing sound would gradually disappear, and after the doctor heard the last sound, the other reading was recorded on the blood pressure meter. Diastolic blood pressure readings represent the lowest pressure in the arteries. It appears in every heartbeat. Diastolic blood pressure is second of the two readings. For example, if your blood pressure readings were 18.7, 1 =7.5 mm Hg, and 12, the 18.7 one was a systolic blood pressure.

Brain

Brain
To the arterial blood supply to the brain will because of chronic hypertension and suffered, and above the similar hurt Q vascular wall thickening and narrowing of the blood vessels, or the formation of a blood clot, prevent certain parts of the blood flow to the brain. The formation of blood clots in the brain called cerebral thrombosis, and can cause stroke. Depending on the different blood vessels, stroke patients may lose their ability to talk, walk or move up the body. Such as carotid artery off the blood clot with blood flow to the brain blood vessel blockage on the formation of the cerebral embolism from anywhere in the blood vessels in the body.
In addition, one or more projections are produced in the middle cerebral artery. These are cerebral aneurysms, which may eventually rupture, causing cerebral hemorrhage, and thus causing another type of stroke, which is usually caused by a more damage than the cerebral thrombosis. Stroke caused by cerebral hemorrhage is more likely to die from a stroke caused by a clot.
It is estimated that the United States has 50 stroke patients annually, of which about 25% -30% of people die, and in the United States, which makes the stroke has become the third common diseases caused by death. Even if there is no death after a stroke, the patient is usually very weak, stroke is the first cause of disability of the elderly in the United states. A stroke can cause paralysis, blindness, deafness, aphonia. Forgetful and a lot of other destructive effects.
80% a 70% of stroke patients with hypertension at the same time. The evidence suggests that a person with a blood pressure and untreated treatment, the probability of a stroke is almost 7 times those of a person who has a normal or high blood pressure. Even normal blood pressure and high blood pressure in patients with mild hypertension risk of stroke is also high. Controlling blood pressure is the best preventive measure to reduce the risk of stroke. Other preventive measures include not smoking, eating less fatty foods, more exercise and taking a small dose of aspirin.
A less common warning sign of a stroke is the so-called small stroke, which is a transient ischemic attack (TIA). Transient ischemic attack unlike explosive stroke that would cause permanent brain damage, small stroke stroke like symptoms lasts only a few minutes to several hours, and go away within 24 hours. Symptoms may include sudden weakness, clumsy, or upper hand. Feet or half face numbness. May also occur in visual impairment, visual acuity and can not speak or speak not coherent. If you have a transient ischemic attack, you should talk with their doctors about how to take preventive measures to prevent another attack, more important is how to prevent the outbreak of stroke onset.
As age increases, many people are worried that they may have to get Alzheimer’s disease, which mainly affects memory and other more advanced brain function, and that the blood supply to the brain may be reduced in older people with a memory disorder or a sudden onset of dementia (a mental decline). Multiple cerebral infarction dementia and Alzheimer’s disease, which can be stable by taking a small dose of aspirin and careful control of blood pressure.
No control of the development of severe hypertension in the course of the development of fiber protein like necrosis, and rapid rupture of blood vessels. This makes the blood and body fluid to leak into the brain, the intracranial pressure increased. Elevated intracranial pressure can cause symptoms such as headache and fatigue, if the pressure has not been reduced, the brain itself will be injured. However, with the great development of blood pressure control technology, this situation is now very rare.
Also, if the extremely dangerous to raised blood pressure, hypertension is a direct result of a called hypertensive encephalopathy of brain diseases. The symptoms of the disease include severe hypertension and disturbance of consciousness, intracranial (skull) with, damage to the retina and more lame attack.
Eye
Eyes are not involved in blood pressure regulation, but there are a lot of blood supply arteries in the eyes. These arteries can be seen in the Department of Ophthalmology when the doctor is examining the retina. If doctors find that these blood vessels rupture or shrink, then other arteries in the body may have similar damage. High blood pressure can lead to retinal (responsible for the reception of images from the lens) degradation, resulting in retinal diseases. The lesions of these ocular arteries showed a similar occurrence of the kidney.

Essential hypertension

 

Essential hypertension

Essential hypertension
About 95% of the cause of hypertension is unknown, so there is no clear treatment. The important evidence indicates that hypertension is caused by the problem of kidney. The study of the kidney showed that a kidney donated by high blood pressure patients would lead to transplant recipients with high blood pressure, and the kidneys donated by normal blood pressure would cause the transplant to disappear. The researchers believe that the early renal function of the early years of the subtle changes in the incidence of hypertension has important influence.
Essential hypertensive patients may have different responses to treatment due to their individual differences. For example, the renal renin in approximately 1/5 of patients with essential hypertension. This is more common among blacks than whites. And a small number of essential hypertension in patients with excessive renin. About more than 1/4 of the patients with essential hypertension of the adrenal glands seem to have problems, their kidneys are hampered by the body to regulate sodium levels. All of these elements are very important. Because they affect people’s health.
Secondary hypertension
For a small part of the high blood pressure, the cause of their hypertension is known, and it may be cured. This type of hypertension is called secondary hypertension, because the rise in blood pressure is indirectly caused by an underlying disease.
If you suspect that you have secondary hypertension, you can judge whether you have these characteristics:
1. Secondary hypertension usually occurs suddenly and without warning.
2. Secondary hypertension is usually the cause of the increase of blood pressure in children.
3. Secondary hypertension often leads to very high blood pressure.
4. The range of blood pressure in patients with secondary hypertension is very large.
5, secondary hypertension is usually accompanied by other unusual symptoms, which can be found.
In most cases, the doctor will direct the treatment of the original disease in the province. If the primary disease is cured, blood pressure will generally return to normal.
You know all kinds of human system for regulating blood pressure. There is no doubt that the defects or diseases of these organs will reduce their ability to maintain normal blood pressure. The most common case one one introduction.

Peripheral resistance

How to overcome hypertension4Peripheral resistance

Arteries play a more active role in regulating blood pressure. The brain is a part of the sympathetic nervous system, which is used to understand the fluctuations in blood pressure through a special sensor on the wall. They feel the pressure of the arterial wall to rise or fall, and this kind of information is transmitted to the brain. When the brain receives a signal of high blood pressure, it sends out information to relax the blood vessels through the collection of nerve cells (blood vessels).
The brain also monitors the amount of oxygen and nutrients the body needs. It regulates blood pressure and blood flow to ensure that the needs of each organization can be met. When the body rests, the brain lowers blood pressure, when the body is under a variety of stress (including the pressure of wake up), the brain will be high blood pressure. The help of the blood vessels to relax the nerve to the changes is to tell the arteries to relax (to lower blood pressure) or to shrink (L hypertension).
As mentioned above, the brain through. Inform. Adrenaline and norepinephrine are the way to get the body ready for the unexpected. These hormones are suitable for a specific organization, like a key to open a lock, the lock is called a receptor, and when the hormone enters, it will start a specific action. The heart also has this “lock”, it is called a receptor. When adrenaline and norepinephrine enter the receptors, the heart beats faster. E- receptors were also in the kidney. When adrenaline and norepinephrine enter these receptors, the kidneys are stimulated to produce renin. There is a drug known as e- receptor blocker, which is the role of the receptor to enter the target and prevent the increase of blood pressure and adrenaline and norepinephrine.
Epinephrine and norepinephrine also enter the a- in the arteries. When this happens, the arteries will shrink, and then the blood pressure will rise. The number of calcium in the muscle cells is dependent on the wall of the arteries and veins. This contraction is caused by a small amount of calcium entering the cell through a tiny channel called the calcium channel. You may have heard of a drug called calcium antagonists, which block the contraction of the vessel wall by blocking the passage of calcium into the cell. The A receptor blocker is a drug that acts by stopping the contraction of adrenaline and noradrenaline.
In the last section, the renin is released from the kidney and other tissues such as the liver, which is released when the body needs to rise. However, renin does not directly affect blood pressure. More specifically, it triggers a chemical reaction that causes one to be converted into another protein, which is converted to angiotensin. If angiotensin encountered vascular angiotensin-converting enzyme, angiotensin converting enzyme, you may heard of angiotensin converting enzyme inhibitor, Yuan is a stop the drugs). This produces another product called vascular angiotensin “. Angiotensin is an active chemical, which can cause arterial contraction and release of aldosterone. Renin angiotensin aldosterone system has not been fully studied, but the study shows that it is essential for the development of hypertension. , a new type of drug called angiotensin blockers is interfering with the effect of this potent chemical.
Many other factors affect the blood vessel resistance. Too much liquid and increase the volume, make the organization become stiff. Arteries must be harder to shrink to the blood into the tissue, blood pressure and so on.
Blood pressure increases with age, and this is because the arteries become more rigid and less flexible, resulting in more resistance to blood flow. Many of the arteries will become narrow and blocked by the accumulation of fat debris over the years, thereby increasing peripheral resistance, which can lead to higher blood pressure.

Regulation mechanism of human blood pressure

Regulation mechanism of human blood pressure
In order to understand. Hypertension is a serious health problem, “this concept, you must first be familiar with the concept of blood pressure. This chapter describes how the body regulates blood pressure, why the body regulates blood pressure, and what impact it will have on the system.
The heart and blood vessels in the body cooperate with oxygen and nutrients to the body, and to remove the waste, such as carbon dioxide, which is exhaled when you breathe. Blood is the transmission medium of these substances. Blood pressure is the result of two kinds of forces in the body that produce the opposite effect. One force is produced when the heart pumps blood, and the other is that the blood flow is generated by the arteries that transport oxygen and nutrients to tissues. The pressure produced during the contraction of the heart is called the systolic pressure, and the pressure of the blood on the wall of the heart is called the diastolic pressure. If the pressure from the heart pumps blood or the resistance (or both) is too large, you get high blood pressure.
Cardiovascular
Blood through the heart of the pump blood function in the body to continue to cycle. The heart pumps the blood to the lungs to carry oxygen, and then the other parts of the body, and then transmitted to the heart through the cardiovascular system. Because the heart and blood vessels are involved in the same cycle, you often hear the name – the cardiovascular system.
Heart to do a small volume (about a clenched fist size) but powerful pump, it makes the blood circulation in the cardiovascular system. It is the most industrious muscle, and it is not the beat of the day and night. The heart beats about 1 times per second, and the total length of the blood pump is 9.6 ~ 16 km long.
The heart is divided into 4 separate chambers, which prevent the blood flow and the mixing of blood between the chambers. The circulation of blood is first received by the first chamber, the right atrium, and once the oxygen of the blood is entered into the atrium, it is pushed into the next chamber of the heart — right ventricle, right ventricle to be. Used in. Blood through the pulmonary artery (the only blood supply of blood in the arteries) directly to the lungs. Lung tissue filters carbon dioxide and provides oxygen for the blood to make it an oxygen rich blood. And then the oxygen enriched blood is returned to the next chamber, left atrium, through the pulmonary veins (the only blood carrying oxygen rich blood). When oxygen enriched blood enters the left atrium, it will be pushed into the final cardiac chamber, left ventricle.
The left ventricle is the main chamber of the heart. As the largest and most powerful heart chamber, the left ventricle will oxygen enriched blood through the body’s largest artery – the great arteries transported to the whole body. Left ventricular work is very hard, so it is about 1.3 cm thick, almost 3 times more than the wall of the right atrium.
Like other organs, the heart also needs oxygen and nutrients to play a role. The heart is supplied with oxygen by the two coronary arteries (left and right) in the large arteries. Used in. Hypoxia blood directly into the right atrium through the coronary veins.
Oxygen enriched blood. Used in. Blood was left and the cardiovascular system was divided into two parts. Arteries send oxygen and nutrients from the heart to the body, while the blood supply to the heart, and the blood flow back to the heart. Microvascular away from the heart, into the tissue in the arteries and veins will be divided into smaller and more fine. The blood from the arteries of the blood vessels is caused by blood from the artery. Capillaries are the smallest blood vessels in the human body, which transport oxygen and nutrients to a single cell and collect the waste products. The lack of oxygen and oxygen rich blood from the blood flow from the capillaries to the micro vein (minimal), and then the blood from here sent back to the heart.
A healthy person’s arteries are strong and elastic. When the heart pumps blood through them, they stretch. In the need to control the flow of blood, the diameter of the artery will change. In order to raise blood pressure, the tiny arteries will shrink and become narrow. You will understand their working principles in the back.
