Question

What is the function of diaphragm in breathing?

Answer 1

When you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. This increases the space in your chest cavity, into which your lungs expand. The intercostal muscles between your ribs also help enlarge the chest cavity. They contract to pull your rib cage both upward and outward when you inhale.

The diaphragm is a flat stretchable structure just under the lungs
