Exercise, nutrition, hormones, and calcium homeostasis
Bone is constantly in conversation with the rest of the body. Muscles load it, the gut supplies its minerals, glands send it hormonal instructions, and in return it lends calcium to the blood whenever levels dip. This topic shows how those exchanges keep both the skeleton and blood calcium in balance.
