Answer:
Your diaphragm contracts and moves downward
Explanation:
When you breathe in, or inhale, your diaphragm contracts and moves downward. This increases the space in your chest cavity, and your lungs expand into it. The muscles between your ribs also help enlarge the chest cavity. They contract to pull your ribcage both upward and outward when you inhale.
