inhale:- the air pressure in the lungs decreases and air moves in. exhale:-air pressure in the lungs increases and air moves out.
When you breathe in, your diaphragm will contract, causing your lungs to expand and suck in air. When you breathe out, your diaphragm will relax, causing your lungs to shrink and force out air.
when air moves out of the lungs, the air pressure decreases
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.
The air moves from the outside into the lungs through the windpipe.
