How does the diaphragm help in breathing?

Answer:

It is a large, dome-shaped muscle that contracts rhythmically and continually, and most of the time, involuntarily. Upon inhalation, the diaphragm contracts and flattens and the chest cavity enlarges. This contraction creates a vacuum, which pulls air into the lungs.

It’s so when you inhale, the diaphragm flattens a little, so the chest cavity can expand I believe.
