Amelia is running a marathon. How do her muscular and skeletal systems work together to allow her to run?

The muscles are attached to the frame by tendons. The skeleton is a frame. We flex out muscles and it moves our frame. Each part of the body that moves is controlled by the muscle above it.

The muscles in her leg relax and contract to move the bones
