A cell called an osteoclast accomplishes bone resorption.

The osteoclasts carry out bone resorption. In contrast, the osteoblasts create new bone.

Resorption

Resorption is the process of dissolving bone and returning its minerals to the bloodstream.

Bone resorption is promoted by the parathyroid hormone, also called PTH. Bone resorption is the process by which osteoclasts break down bone and release the minerals, resulting in a transfer of calcium from bone fluid to the blood.
