The primary function of the skeletal system in humans is to provide structural support, protect internal organs, and enable movement. It consists of bones, cartilage, and ligaments, forming a framework for the body. Additionally, the skeletal system produces blood cells in the bone marrow and stores essential minerals like calcium and phosphorus. By facilitating movement alongside the muscular system, the skeletal system plays a critical role in overall health and mobility. Beyond its physical functions, the skeletal system also contributes to the body’s shape and posture, emphasizing its importance in maintaining human biomechanics.
