what is the functions of calcium in our body
Answers
Answer:
Calcium is very essential in muscle contraction, oocyte activation, building strong bones and teeth, blood clotting, nerve impulse, transmission, regulating heart beat and fluid balance within cells.
Explanation:
About 99% of the body’s calcium is stored in the bones, but cells (particularly muscle cells) and blood also contain calcium. Calcium is essential for the following:
Formation of bone and teeth
Muscle contraction
Normal functioning of many enzymes
Blood clotting
Normal heart rhythm
The body precisely controls the amount of calcium in cells and blood. The body moves calcium out of bones into blood as needed to maintain a steady level of calcium in the blood. If people do not consume enough calcium, too much calcium is mobilized from the bones, weakening them. Osteoporosis can result. To maintain a normal level of calcium in blood without weakening the bones, people need to consume at least 1,000 to 1,500 milligrams of calcium a day.
The level of calcium in blood is regulated primarily by two hormones:
Parathyroid hormone
Calcitonin
