Explain how osteoclasts and osteoblasts remodel bone.
Bones are the rigid living tissue that makes up the skeletal system of the body. The various functions of the bone include protection of the internal organs, production of white and red blood cells, providing structure and support to the body, and facilitating mobility. The protein collagen forms the major framework of the bone along with the mineral calcium phosphate which provides strength to the framework.
The bone is made up of three parts namely the compact tissue which is the outermost tissue that is extremely hard, the cancellous tissue which is spongy in nature and occurs inside the bone, and the subchondral tissue which exists at the ends of the bone and is covered by cartilage. Bones are made up of four different kinds of cells namely the osteoblasts, osteoclasts, osteocytes and osteogenic cells.
