Final answer:
The muscular and skeletal systems work together to support and allow for movement. Bones protect the body's organs and muscles contract to move the bones, enabling various movements.
Step-by-step explanation:
The muscular and skeletal systems work together to provide support and allow for movement. The bones of the skeletal system protect the body's organs and support its weight. When muscles contract, they pull on the bones, causing movement. For example, when you run, the muscles in your legs contract to move your leg bones, allowing you to run. The skeletal system provides a system of levers that allow body movement, while the muscular system provides the force that moves the levers. This collaboration between the two systems enables various types of movements, such as standing, walking, running, and gripping objects.
