People's acid-base balance needs to be kept at a certain level, and excessive or insufficient acid-base is produced in the body, which causes the change of blood pH value. This state is called acid-base imbalance. Maintaining basic life activities mainly depends on the fine acid-base balance or internal environment stability in the body. Even a small imbalance may greatly affect the metabolism of the body and the function of important organs.
Extended data:
The pH value of normal blood is always kept at a certain level, and its change range is very small. The relative stability of blood pH is one of the basic conditions for normal physiological activities.
Every day, in the process of metabolism, the body will produce a certain amount of acidic or alkaline substances and continue to enter the blood, which may affect the pH of the blood. However, the pH value of blood is still constant between pH 7.35 and 7.45. A healthy body is like this. In the process of disease, the human body is still trying to keep the pH of blood within this narrow range.
The reason why the blood pH value is so stable is that the human body has a set of mechanisms to adjust the acid-base balance. First, it depends on some acidic or alkaline substances in the blood and a certain proportion of buffer system. However, the proportion remains unchanged, and it depends on the adjustment of organs such as lungs and kidneys to eliminate excess acid or alkali and maintain the relative balance of pH in the body.
