WHAT does the diaphagram do?

Answer 1

It's a muscle in your chest that expands your chest size when you breath in and decreases size when you breathe out. (i think you might want to double check.).

Hope this helps!

Answer 2

The diaphragm is a dome-shaped muscle located beneath the lungs that plays a crucial role in breathing. When you inhale, the diaphragm contracts and moves downward, creating more room for the lungs to expand and fill with air. When you exhale, the diaphragm relaxes and moves back up, helping to push the air out of the lungs.
