How to overcome hypertension2

Cardiac output
The heart is controlled by the brain, which allows blood to flow at a steady rate of 5.5 liters per minute. If the fluid overload, blood will be increased, cardiac output and blood pressure were all increased. The greater the amount of fluid, the more difficult the heart and blood vessels to make the blood flow. Diuretic is a common drug for treating hypertension, which works by reducing the amount of fluid in the body.
Kidney (two in the back of the waist of the bean shaped organs) to control the amount of fluid circulation in the body. They control the amount of fluid in a person’s urine, either by keeping them in a salt or by keeping them in water. Usually if you eat too much salt, the kidney will emit an excess of sodium and the relative amount of water. However, if your kidneys are unable to rule out the excess sodium, your body will keep the moisture, which will increase the amount of blood and elevated blood pressure.
There are two important chemical substances and maintain the balance of water and sodium in the body. An enzyme called renin (which is secreted by the kidneys, which can accelerate the rate of chemical reaction in the body). The amount of the kidney in the body fluid (which is based on the amount of salt consumed) and the blood pressure applied to the kidney to determine when to release the renin. The lower the pressure, the more the ridge is released. Renin can speed up the rate of angiotensin (a protein in the blood) to a blood vessel. In the next chapter, the reaction and the results are presented.
The side product of the renin can also stimulate the adrenal gland, the right side of the kidney, to produce a chemical that is related to the level of sodium in the body. This chemical is a hormone called aldosterone. And the enzyme is not the same, the hormone will enter a single cell and to serve as a chemical messenger to their target tissues. Aldosterone enters the blood from the adrenal gland and then enters the kidney. The chemical information that aldosterone gives to the kidneys is to retain more sodium and water. The holding capacity of sodium and water increased blood pressure.
Other hormones that affect cardiac output and blood pressure. When you are in any stressful situation, your brain is in the middle of a sudden condition. One way is to send the information to an organ through the sympathetic nervous system. The sympathetic nervous system is a part of the vegetative nervous system, while the vegetative nervous system belongs to the nervous system. The system is responsible for controlling involuntary movements such as breathing, digesting food and controlling blood pressure.
When the adrenal gland is received from the sympathetic nervous system, they secrete epinephrine and norepinephrine, which have different effects on the body. Adrenaline makes the heart beat faster, and that’s what’s going on in the next chapter. As you would like to be the heart of the heart of the sudden rise in heart rate will increase the output of the heart, so high blood pressure.
