Skeletal Function The skeleton, comprised of a network of bones held together at joints, has many functions. The skeleton protects vital internal organs. For example, the skull forms a protective encasement for the brain. The rib cage provides protection for the heart and lungs. Flat bones, such as those of the skull, ribs, and breastbone, produce blood cells. All bones are storage areas for inorganic calcium and phosphorus salts. Bones also provide sites for attachment of muscle, tendons,...
