The function of the skeletal system in humans is to provide structural support, protect vital organs, enable movement, and store minerals. The skeletal system consists of bones, cartilage, ligaments, and joints. It serves as an anchor for muscles, allowing movement through coordinated action. Additionally, the bones store essential minerals like calcium and phosphorus, which are vital for various biological functions. The skeleton also plays a crucial role in producing blood cells within the bone marrow, contributing to overall health and homeostasis.
