99% of calcium in human body is deposited in bones and teeth, which promotes their growth and maintains their shape and hardness; L% exists in blood and soft tissue cells and plays a role in regulating physiological functions.
The physiological function of calcium ion determines its importance to human life activities:
Calcium ion plays an important role in blood coagulation. When calcium is lacking, blood coagulation will be hindered, and symptoms such as gingival bleeding, subcutaneous bleeding, irregular uterine bleeding, menorrhagia, hematuria and hematemesis will appear in human body.
Calcium ion plays an important role in nerve and muscle excitation and nerve impulse conduction. When calcium is deficient, the human body will have symptoms such as nerve conduction block and abnormal muscle tone.
Calcium ion plays an important role in cell adhesion and maintaining cell membrane function. Cell membrane is not only a barrier to cell contents, but also a carrier for all kinds of essential nutrients and oxygen to enter cells. The normal content of calcium ions can ensure that the cell membrane "pumps" nutrients into the cells smoothly.
Calcium ion can activate the enzyme reaction in human body. As we all know, enzyme is a catalyst for the metabolic process of various substances in the human body and an important life substance in the human body. Calcium deficiency will affect the normal physiological and metabolic process.
Calcium ions play a decisive role in the secretion of endocrine gland hormones in human body, and are very important for maintaining the functions of circulatory, respiratory, digestive, urinary, nervous, endocrine and reproductive systems and organs.
In a word, calcium is an indispensable trace element for human body. It is not only the constructor of the body, but also the regulator of the body and the source of our human life.
