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
Exhalation, similar to inhalation, consists of the standard tidal volume as well as the potential for an expiratory resolve volume (ERV). The ERV can be thought of as the amount of air that is pushed out after a normal breath if you were to exhale as much as possible. Another commonly used term is vital capacity (VC).
