The skeletal system is the framework of bones that supports and shapes the body. It consists of 206 bones in adults, along with cartilage, ligaments, and tendons. This system provides structure, protects vital organs, and allows for movement by serving as attachment points for muscles. In addition to support and protection, the skeletal system plays a crucial role in producing blood cells and storing minerals like calcium and phosphorus. The bones are living tissues that constantly undergo remodeling, ensuring they remain strong and healthy throughout a person's life.
