How Do Our Bodies Move?

The video explains how exercise is crucial for health and how the body moves using three systems: muscular, skeletal, and nervous. The muscular system, made of muscles, allows movement by contracting and relaxing. The skeletal system, composed of bones, supports the body and works with muscles via tendons. The nervous system, led by the brain, sends signals to muscles to control movement. Together, these systems enable actions like picking up an apple.
