Exploring How Our Bodies Move

The video explains how exercise is crucial for health and how the body moves using three systems: muscular, skeletal, and nervous. Muscles contract and relax to move bones, which are supported by the skeleton. The brain, part of the nervous system, sends signals to muscles to initiate movement. The video answers a viewer's question and encourages further engagement.
