The skeletal system, composed of bones, cartilage, tendons, and ligaments, plays a crucial role in the overall structure and function of the human body. It provides support for the body, allowing us to stand, sit, and move. It also serves as a protective framework for vital organs, such as the brain, heart, and lungs. Additionally, the skeletal system is responsible for producing blood cells and storing essential minerals.
