The skeletal system provides shape, support, protection of organs, enables movement, and stores minerals for the body. It is made up of bones, cartilage, and joints. Bones protect important organs like the brain, heart, lungs, and spinal cord. Without bones, the human body would not have structure and would be formless. The skeletal system works together with other body systems like the muscular and circulatory systems.
