Which system supports the body and protects vital organs while facilitating movement?

1. Nervous system

2. Circulatory system

3. Skeletal system

4. Muscular system

The correct answer is: Skeletal system

The skeletal system is the framework of the body and serves several essential functions that are critical for maintaining overall health. It supports the body by providing structure and shape, allowing us to stand upright and maintain posture. Additionally, the skeletal system protects vital organs such as the heart, brain, and lungs by encasing them in hard bone structures, reducing the risk of injury. Moreover, it works in conjunction with the muscular system to facilitate movement. Muscles attach to bones, and when they contract, they pull on the bones to produce movement. This interaction is crucial for activities such as walking, running, and lifting. Therefore, the skeletal system's role in providing support, protecting vital organs, and enabling movement makes it foundational to the body's overall functionality. Understanding this is critical for anyone studying first aid or health-related fields, as it highlights the importance of bone integrity in emergencies.
