Exhalation is the flow of the breath out of an organism. In humans it is the movement of air from the lungs out of the airways, to the external environment during breathing. This happens due to elastic properties of the lungs, as well as the internal intercostal muscles which lower the rib cage and decrease thoracic volume. As the thoracic diaphragm relaxes during exhalation it causes the tissue it has depressed to rise superiorly and put pressure on the lungs to expel the air. During forced exh
1 The diaphragm is a large, sheet-like muscle at the bottom of your chest cavity. 2  It helps you exhale and inhale by moving up and down, respectively. 3  When your diaphragm contracts (moves up), you inhale air. 4  When your diaphragm relaxes (moves down), you exhale air.
