Calcium and Phosphate Homeostasis

Bone calcium: A vast majority of body calcium is in bone. Within bone, 99% of the calcium is tied up in the mineral phase, but the remaining 1% is in a pool that can rapidly exchange with extracellular calcium. As with calcium, the majority of body phosphate (approximately 85%) is present in the mineral phase of bone.
