What do all the bones do?

4 Functions of Bones Support Your skeletal system protects and supports you. Your heart and lungs are shielded by your ribs, your spinal cord is protected by your vertebrae, and your brain is protected by your skull. Storage Bones store minerals such as calcium and release them into the surrounding tissues to help the nerves and muscles function properly. The cavities inside your arm and leg bones also store fat that can be used for energy. Movement Skeletal muscles, which are attached to the bones by tendons, pull on the bones to produce movement. Without bones, you would not be able to sit, stand, walk or run. Blood Cell Formation Red marrow found in spongy bone of the legs, arms, ribs, sternum (breastbone), and vertebrae (backbones) makes red & white blood cells.
