Human skeleton
An adult female human skeleton. The skeleton provides six main functions: (1) Provide shape and support of the body; (2) provide an attachment surface for muscles and tendons which together enable (3) movement of the body; (4) protection of many vital organs, such as the brain, spinal cord, and heart; (5) the generation of blood cells, which takes place in red bone marrow; and (6) storage of calcium and iron.Image credit: Mariana Ruiz
