Calcium is also divided into bone calcium and blood calcium. Bone calcium refers to the content of calcium in bones, and blood calcium refers to the concentration of calcium in blood. If bone calcium is deficient, it will lead to osteoporosis. If the blood calcium is insufficient, it will lead to hypocalcemia and convulsion. What is the difference between bone calcium and blood calcium?

1 exists in different forms. Calcium in blood mainly exists in the form of ionized calcium salt. Calcium in bones mainly exists in the form of calcium carbonate and calcium phosphate.

2, the content is different. Although the content of calcium salt in blood seems to be more, it is far lower than that in bones. Bone is the storage warehouse of calcium and phosphorus in human body.

3. The stability is different. The content of calcium salt in blood will fluctuate greatly with the metabolism of human body. For example, when a patient vomits, has diarrhea or perspires a lot, it may cause the calcium content in the blood to drop sharply in a short time. In addition, if patients eat high-calcium food, it may also lead to a short-term increase in calcium, and the changes in calcium in bones will be relatively alleviated.

4, the form of supplement is different. Calcium in the blood can be supplemented by food. In addition, when the calcium salt in blood decreases for a short time, the calcium salt in bone can be released into blood for a short time. However, calcium in bones can only be gradually deposited into bones through calcium salts in blood.
