What is the primary function of the skeletal system?

The primary function of the skeletal system is to provide support and protection to the body. The skeleton serves as the framework that supports the body's structure, allowing us to maintain an upright posture and giving shape to the body. It also plays a crucial role in protecting vital organs. For instance, the skull encases the brain, the rib cage shields the heart and lungs, and the vertebral column safeguards the spinal cord.

In addition to support and protection, the skeletal system is involved in storing minerals and producing blood cells in the bone marrow. While aiding in movement is a function of the skeletal system, it is primarily a support system that works in conjunction with muscles, tendons, and ligaments to facilitate movement. This distinction emphasizes that support and protection are at the core of what the skeletal system is designed to accomplish.
