Which body system contributes to the movement of the body by working with the skeletal system?

1. Lymphatic

2. Respiratory

3. Muscular

4. Nervous

The correct answer is: Muscular

The muscular system is the primary contributor to the movement of the body, as it consists of all the muscles that facilitate motion. Muscles work in conjunction with the skeletal system, which serves as a framework for the body. When muscles contract, they pull on the bones, creating movement at the joints. This interplay allows for a wide range of movements essential for various physical activities, from simple actions like walking to more complex tasks like dancing or playing sports. While the other systems play vital roles in overall body function, they do not directly contribute to movement in the same way. The lymphatic system is primarily involved in fluid balance and immune functions, the respiratory system handles gas exchange and breathing, and the nervous system controls and coordinates body functions, including the signal for muscles to contract. However, it is the muscular system that acts directly to produce movement alongside the skeletal framework.
