Function of Bone

Table 35.1 Functions of Bone 1. Movement. Bones interact with skeletal muscle and change or maintain positions of the body and its parts. 2. Support. Bones support and anchor muscles. 3. Protection. Many bones form hardened chambers or canals that enclose and protect soft internal organs. 4. Mineral storage. Bones are a reservoir for calcium and phosphorus ions. Deposits and withdrawals of these ions help maintain their concentrations in body fluids. 5. Blood cell formation. Only certain bones contain the tissue where blood cells form.
