Calcium is a very important element in the body. The number of cells dividing and multiplying gradually increases, and the function of single cells gradually changes, all of which require the participation of calcium. Calcium enters cells, emits radio waves and spreads all over the body’s nerve fibers, forming human intelligence. The input of network information can only be transmitted to all parts of the body through the activity of calcium.At the cellular level, calcium acts as a coupling factor between nerve and muscle excitation-contraction, promotes the release of neural mediators and a regulator of hormone secretion from endocrine and endocrine glands, conducts nerve impulses, and maintains heartbeat rhythm. What is calcium Why is it important for the body
Calcium also has a sedative effect. When the calcium concentration in body fluids decreases, the excitability of nerves and muscles increases, and the muscles experience spontaneous contractions, and convulsions occur in severe cases. When the calcium concentration in body fluids increases, the excitability of nerves and muscles is inhibited.
Calcium can promote the activities of a variety of enzymes in the body, and is a variety of enzyme activators, such as lipase, amylase, etc., which are regulated by calcium ions. When there is a lack of calcium in the body, protein, fat and carbohydrates cannot be fully utilized, resulting in malnutrition, anorexia, constipation, and growth retardation.
