It increases and decreases the size of chest cavity.
We know that air flows from high pressure to low pressure. When we inhale, the diaphragm moves down, increasing the size of the chest cavity and creating a low pressure area, so air rushes to the lungs.
When we exhale, the diaphragm moves up to its regular position, reducing the size of the chest cavity and creating a high pressure area. So, air rushes out of the lungs.
