As calcium (Ca²⁺) is one of the main components of our bones, large amounts are present

Bone Metabolism: Bone formation and bone resorption (Part 1)

BONE FORMATION AND BONE RESORPTION

Fig. Bone Cells

Living bone is constantly being remodeled. The state of our bones is always close to an equilibrium between bone formation and bone resorption. In childhood and during the teens, bone formation is slightly ahead. We reach peak bone mass in the twenties, and from then onwards, resorption has the upper hand. There are two reasons for the
