What is the primary function of the skeletal system?

The primary function of the skeletal system is to provide support and protection for internal organs. The skeletal system consists of bones, cartilage, and ligaments that give the body its shape, support its structure, and enable movement in conjunction with the muscular system. Additionally, it protects vital organs such as the brain, heart, and lungs from injury. For example, the rib cage encases the heart and lungs, while the skull safeguards the brain.

Support is crucial for maintaining posture and the integrity of the entire body structure, allowing for efficient movement and functioning of other bodily systems. While other systems, such as the circulatory system, are responsible for transporting nutrients, and the endocrine system for producing hormones, these functions are separate from the primary role of the skeletal system.
