What happens when you contract your diaphragm?
This lesson looks at how your body changes when you inhale and exhale. It's an automatic process, but we can also take control of it. It changes based on what our needs are. It never fully deflates, and you can exchange a large volume of air with each breath. It will also show how breathing patterns are analyzed and categorized.
