Maintaining blood balance (homeostasis)
In order to function well, the body must be able to maintain a certain balance.It is speculated that a high protein diet has a Blood Balance Formula Review favorable effect in diabetes The concentration of mineral salts in the blood, the blood pH and the proportion of water in the human body are parameters monitored by the pituitary gland, a gland at the base of the brain. These parameters can be changed by the kidneys , lungs , and sweat glands .
The action of the lungs
The lungs help maintain an adequate blood balance by removing CO 2 which, in too large a quantity, lowers the pH of the blood which is usually 7.4. However, when you exercise without getting good oxygen, the blood level of carbon dioxide increases, bringing the pH to below 7.35. It is important that the pH remains stable so that the chemical reactions taking place in the body are carried out effectively. To remedy this, the respiratory rate will accelerate, which eliminates more CO 2 so that the pH rises. If that's not enough, the kidneys can also adjust the pH by producing more acidic urine.
Kidney action
The kidneys play a very important role in maintaining blood balance since they are responsible for filtering the blood as well as removing certain potentially harmful substances from the body. If, for example, we drink a lot of water, the mineral salts of the blood will be more diluted and therefore their concentration will be lower. In response to this, the pituitary gland will instruct the kidneys to remove more water from the bloodstream, which will bring the concentration of mineral salts back to normal. Conversely, if you eat too much salt, the kidneys will absorb less water and more mineral salts, in order to decrease its concentration.
The action of the sweat glands
The sweat glands, on the other hand, can restore blood balance by varying the constitution of sweat. It contains water, nitrogenous waste and mineral salts. You could even say that sweat has the same composition as urine, but more diluted. During sustained physical activity where there is heavy sweating, a lot of water is lost through sweat and in response, the kidneys will remove less water from the bloodstream.
The regulation of balance takes place immediately through the intervention of buffer systems, short term by the lung, long term by the kidney.
The lungs , by excreting carbon dioxide through the respiratory tract, modify the pCO 2 of arterial blood.
