The main function of the skeletal system is to provide support and structure to the body. It consists of bones, cartilage, ligaments, and tendons that work together to give our body shape and protect our vital organs. The skeletal system also plays a crucial role in movement by providing attachment points for muscles, allowing us to perform various actions such as walking, running, and jumping. Additionally, the skeletal system produces red blood cells in the bone marrow, stores minerals like calcium and phosphorus, and provides a framework for our body's overall development and growth.
