Question

Inhalation and exhalation move air into and out of the lungs. what happens when you inhale and exhale?

Answer 1

When you breathe in your diaphragm contracts and moves downward.this increases the space in your chest cavity into which your lungs expand.the intercoastal between your ribs also help enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale
