The diaphragm muscles contract and relax pulling the diaphragm down and then releasing it.
When we inhale, our diaphragm muscles contracts and flattens. When we exhale, they relax and arch upwards.

∙ 12y agoThe diaphragm, when relaxed, is a dome shaped muscle. During inspiration, the the diaphragm contracts and flattens out. This has the effect of drawing the lungs down with it and increasing the intrapulmonary volume (i.e. the volume inside the lungs). When the volume increases, the pressure inside the lungs drops creating a partial vacuum. As the air pressure outside is greater than the air pressure in the lungs, air will flow down its pressure gradient into the lungs inflating the alveoli.
