They absorb (or resorb) bone.
Bone is active living tissue that is constant remaking itself. The osteoclasts break down and resorb old bone while osteoblasts lay down new bone to take its place.
Osteoclasts are responsible for the break down bone. Osteoclasts release minerals that result in a transfer of calcium from bone fluids to the blood stream which is the re-absorption process.
osteoclasts break down bones, osteoblasts build them up
osteoclasts
OsteoClasts Crumble bone, while OsteoBlasts Build Bone.
Several cells have this function: the osteoclasts which break down bone and the osteoblasts which build bone.
Bone resorbing cells are known as osteoclasts. Immature bone cells are referred to as osteoblasts. Mature bone cells are called osteocytes.
Osteoclasts are large, multinucleated cells found in bone tissue. They are responsible for the breakdown and resorption of bone by secreting enzymes and acids that dissolve the mineralized matrix of bone. Osteoclasts are derived from the fusion of monocytes/macrophages and are involved in bone remodeling and repair.
Osteoclasts cut away the calcium from the bones.
osteoclasts
Ossification.
Osteoclasts degrade bone surfaces so that osteoblasts can produce new bone Also Osteoclasts realese calcium and phosphorus into the blood stream
osteoclasts are cells that dissolve bone cells.
