Which body system is responsible for providing structure and support?

The musculoskeletal system is the body system responsible for providing structure and support. This system comprises bones, muscles, cartilage, tendons, and ligaments, working together to give shape to the body, protect vital organs, and enable movement. Bones form the rigid framework of the body, while muscles attach to bones to facilitate motion. In addition to support and locomotion, the musculoskeletal system plays a crucial role in maintaining posture and balance.

The other systems listed do not primarily function to provide structure and support. The nervous system is mainly involved in transmitting signals throughout the body to coordinate responses and processes. The immune system protects the body from infections and diseases, focusing on defense rather than structure. The endocrine system is responsible for hormone production and regulation, influencing bodily functions like metabolism and growth but not specifically providing structural support.
