Our lungs are not in our stomach, so how is it possible to expand our stomach when breathing in?

Question

What exactly is happening when we expand our stomach when breathing and what specifically are we doing differently when we breathe through our chest?

Answer 1

All your bits inside your torso take up a specific amount of space. When you take a breath your lungs are expanding because a muscle below your lungs, the diaphragm, pulls them downward. Toward your stomach. Which pushes your stomach out of the way because there’s only so much space. Fortunately, your belly (and your ribs to a lesser extent) can expand to accommodate all this pushing and pulling as you breathe.
