Where is Calcium Stored in the Body?
Calcium is the most abundant mineral in the human body, and about 99% of it is stored in the bones and teeth. Calcium is essential for the proper development and maintenance of bones, as well as for the proper function of muscles, nerves, and blood vessels. Small amounts of calcium are also found in the blood and extracellular fluid.
The body carefully regulates calcium levels in the blood, keeping them within a narrow range. If blood calcium levels drop too low, the body will release calcium from the bones to maintain the proper level in the blood.
Calcium absorption occurs in the small intestine, and is facilitated by vitamin D. Calcium is excreted in the urine and feces.
