Which system works together with the skeletal system to enable movement?

The muscular system is integral to movement in the body because it consists of all the muscles that facilitate motion. When muscles contract, they pull on bones, which are part of the skeletal system, to create movement at the joints. This interaction allows various actions, such as walking, running, or any physical activity requiring movement.

Each muscle works in conjunction with the skeletal system by either contracting (shortening) or relaxing (lengthening) to produce the necessary movements. For example, the biceps and triceps work together to enable bending and straightening of the elbow. This collaboration between the muscular and skeletal systems forms the foundation of locomotion and overall physical activity.

Other systems, like the respiratory, endocrine, and circulatory systems, have functions that support overall bodily health but do not directly enable movement in the same way the muscular system does in conjunction with the skeletal system. The respiratory system is crucial for breathing, the endocrine system regulates hormones, and the circulatory system is responsible for blood flow, but none of these systems produce movement directly.
