Air moves into the lungs when the diaphragm is flattened. The diaphragm is relaxed (arched) during expiration.
True
I think you meant move air into the lungs. The muscle is the diaphragm.
well, i guess it would be you diaphram since it pulls air into your lungs.
It's just below the lungs and is essential for breathing. The diaphram is what moves causing the lungs to expand and contract making air come in and out.
when you contract your diaphram, or the lung muscle, your lungs become somewhat empty. this is called a partial vacuum. this is something that air, water, anything that can go in try to fill. the lungs, now a vacuum, pull stuff, supposed to be air!,into the lungs.
It is the muscle below the lungs and it essentially allows you to breath. It goes up and down, changing the pressure inside your body which allows air to flow in your 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.
inhale:- the air pressure in the lungs decreases and air moves in. exhale:-air pressure in the lungs increases and air moves out.
the expansion and relaxation of your diaphram.
Actually, air isn't forced into the lungs my the contraction of any muscle, but by the relaxation of the Diaphragm, along with the Intercostalis muscles on the ribs and the smooth muscle on the lungs. When your diaphragm contracts, it pushes air out of your lungs. When it relaxes, air is drawn in to the lungs. The intercostalis muscles also help move the ribs when the lungs move as your breath. There is one set on the ribs and one set in between each rib.Hope this helps!
it contracts when you exhale because it is pushing the air out of your lungs.
when air moves out of the lungs, the air pressure decreases
