The skeletal system is primarily responsible for protecting organs and allowing for body movement. It provides a rigid framework that supports the body and protects vital organs such as the brain, heart, and lungs. The bones of the skeleton act as shields for these organs against injury. In addition to protection, the skeletal system works in conjunction with the muscular system to facilitate movement. Muscles are attached to bones, and when they contract, they pull on the bones, enabling motion at the joints.

While the nervous system plays a crucial role in controlling body movements by sending signals to the muscles, it does not provide structural support or protection to the organs. The muscular system is essential for movement, but it relies on the skeletal framework to perform properly. The circulatory system is vital for transporting blood, nutrients, and oxygen throughout the body, but it does not directly contribute to the protection of organs or the mechanics of body movement. Thus, the skeletal system is the correct answer as it encompasses both aspects of organ protection and movement facilitation.
