As the diaphragm contracts or retracts, the interior pressure of the lungs changes. As this pressure change occurs, the air pressure outside of the body remains unchanged. The resulting lack of pressure equality forces the air in or out of the lungs to maintain an equilibrium in the body pressure.
when air moves out of the lungs, the air pressure decreases
The air moves from the outside into the lungs through the windpipe.
the lungs will moves down when breathe out air
breathing.
the diaphragm
inhale:- the air pressure in the lungs decreases and air moves in. exhale:-air pressure in the lungs increases and air moves out.
The diaphragm moves down to make the lungs expand (inhalation)
Air moves into the lungs when the diaphragm is flattened. The diaphragm is relaxed (arched) during expiration.
Lungs.

The opposite. When you exhale, the diaphragm moves upward to push the air out of the lungs.
The muscle is the "diaphragm" muscle. It is located beneath the lungs. When it moves down and away, it creates lower pressure around the lungs, and the air pressure outside the body flows into the lungs. When it moves up and in, it compresses the lungs, increasing the pressure to force the air back out.
