The Thoracic Diaphragm muscles the lungs open, creating a pressure differential: the air in the lungs is lower pressure than the air outside, so air rushes in. When you exhale, the opposite happens. If there are problems with the diaphragm, secondary breathing occurs with flexion of the chest and abdominal muscles. This doesn't work as well as primary breathing and it requires a lot more excercise -- and oxygen -- to do it.
