By Jay Patrick Our whole bodies are in a continuous state of flux. This even includes the skeleton, which is constantly discarding old cells and adding new ones.
Bone remodels itself to remove worn cells and to maintain the proper amount of calcium in the blood.
Indeed, bone is the body s storage point or reservoir for calcium. However, some parts of a bone s shaft, consisting of compact bone, may never be remodeled. But bone gets full strength and flexibility from the connective tissue, which intertwines with it, and serves to interface each bone with other bones. Vitamin D, which is produced on the skin under sunlight, or may be ingested in the diet, is widely known to be essential to the deposition of minerals in the bone structure. These minerals are chiefly calcium and phosphorus.
