The primary function of the skeletal system in the body is to provide structural support, protect vital organs, and facilitate movement. Comprising bones, cartilage, ligaments, and tendons, the skeletal system forms the framework that gives shape to the body. It supports the weight of the body and allows for movement by acting as levers when muscles contract. Additionally, the skeletal system plays a role in producing blood cells through bone marrow and storing essential minerals such as calcium and phosphorus, contributing to the body’s overall homeostasis.
