Osteoclasts are the bone cell that destroys bone. This allows bone  remodeling, and allows the skeletal system to act as a reservoir  for minerals to maintain blood mineral â¦ levels. Bone cells that are involved in reabsorption and breakdown of the  bone matrix are referred to as osteoclasts.

There are two types of cells that work together to alter your bones in response to many environmental factors: osteoblasts and osteoclasts. Bone is a hardened matrix composed mainly of the mineral calcium phosphate and the protein collagen. This matrix is produced and secreted by osteoblasts.
