Bone and Calcium | Boundless Anatomy and Physiology

The process of bone resorption by the osteoclasts releases stored calcium into systemic circulation and is an important process for regulating calcium balance. As bone formation actively fixes circulating calcium in its mineral form by removing it from the bloodstream, resorption actively unfixes it, thereby increasing circulating calcium levels.
