The primary function of the skeleton in the human body is to provide structural support and protection to vital organs. The skeleton consists of bones, cartilage, ligaments, and joints that work together to form a rigid framework. This framework supports the body’s structure, allowing for movement by serving as attachment points for muscles. Additionally, the skeleton protects delicate organs, such as the brain and heart, and plays a crucial role in the production of blood cells within bone marrow. Furthermore, bones store essential minerals like calcium and phosphorus, making the skeletal system vital for overall health and functioning.
