What is the primary function of the skeletal system?

The primary function of the skeletal system is to provide structure, support, and protection to the body. This system consists of bones and cartilage that together form a rigid framework. This framework not only gives shape to the body but also supports soft tissues and organs, ensuring they are held in place. Additionally, the skeletal system protects vital organs; for instance, the skull encases the brain while the ribcage shields the heart and lungs.

Furthermore, the skeletal system plays a critical role in facilitating movement, but it does so in conjunction with the muscular system, where bones act as levers and joints as pivots. While aspects like regulating body temperature and transporting nutrients and oxygen are essential functions performed by other systems (such as the integumentary and circulatory systems, respectively), they do not fall under the primary functions of the skeletal system. Thus, the emphasis on structure, support, and protection highlights the core roles that the skeletal system serves in maintaining the body's integrity and function.
