"The process of dissolving bone and returning its minerals to the bloodstream is known as resorption." It is the process by which osteoclasts break bone tissue and release the minerals, causing a transfer of calcium from bone tissue to the blood.
In the cycle of bone growth, resorption is the breakdown and assimilation of old bone. It remove hard bone tissue during the resorption (remodeling) process, and osteoblasts then lay down new bone cells.
