What is the main function of the skeletal system?

The main function of the skeletal system is to provide support and structure to the body. It serves as a framework that gives shape to the body, allowing us to stand upright and maintain our posture. The bones of the skeletal system support vital organs, protect them from injury, and allow for the attachment of muscles, which plays a key role in overall stability. Additionally, the skeletal system is crucial in facilitating movement, as it works in conjunction with the muscular system. However, the primary role remains providing the necessary support that allows the body to function as a cohesive unit. Other functions of the skeletal system, such as blood cell production in the bone marrow and mineral storage, are secondary to its primary role in support and structure.
