what happens to your diaphragm when you inhale

When you inhale, your diaphragm contracts and flattens , moving downward. This gives your chest cavity more space, lowers pressure inside the chest, and helps air flow into your lungs.

Quick Scoop

• At rest: the diaphragm sits in a dome shape under the lungs.

• When you inhale: it tightens, flattens, and moves downward.

• Result: the chest cavity expands, pressure drops, and air is drawn into the lungs.

• When you exhale: it relaxes and moves back up to its dome shape.

If you want, I can also turn this into a one-sentence social post or a super simple diagram-style explanation.
