Answer:
Bone is considered both a tissue and an organ. It is a tissue because it is a collection of cells, such as osteocytes, osteoblasts, osteoclasts, and osteocalcin, that work together to form the structure and function of bone. It is also considered an organ because it serves a specific function in the body, namely to provide support and protection for the internal organs and muscle tissue. Bone plays an essential role in maintaining the stability of the skeleton and protecting vital internal organs from injury. It also serves as a reservoir for calcium and other minerals that are necessary for optimal health.
