When the diaphragm contracts, it moves down and expands the chest cavity, which creates a vacuum that draws air into the lungs. When the diaphragm relaxes, it moves up and compresses the chest cavity, which pushes air out of the lungs. The movement of the ribs are not the primary force behind exhaling.
