eli5 Why do our stomachs move when we breathe?

In: Biology

There is this muscle called the diaphragm. It sits up under the lungs and it is pushes down when we breathe in and pushes back up when we breathe out.

Expanding the belly is done by the diaphragm pushing down really far and making your abdominal muscles move too!
