The main purpose of the skeletal system is to provide structure and support to the body, protect vital organs, and facilitate movement. It interacts with the muscular system by serving as a framework to which muscles attach. When muscles contract, they pull on bones, which results in movement of the body. Thus, the skeletal and muscular systems work together to enable locomotion and various physical activities.
The correct response is: To provide structure and allow movement; muscles attach to bones and cause movement.
