The primary role of the skeletal system in movement is to provide a structured framework that supports the body and facilitates locomotion. Composed of bones, cartilage, and ligaments, the skeletal system works in conjunction with muscles to enable various movements. When muscles contract, they pull on bones, which act as levers, allowing for actions such as walking, running, and lifting. Moreover, the skeletal system protects vital organs, stores minerals like calcium and phosphorus, and produces blood cells in the bone marrow. Therefore, it is essential not only for movement but also for overall bodily functions and health.
