Key Points
- In humans, exhalation is the movement of air out of the bronchial tubes, through the airways, to the external environment during breathing.
- Exhalation is a passive process because of the elastic properties of the lungs.

Breathing - Wikipedia
The lungs are not capable of inflating themselves, and will expand only when there is an increase in the volume of the thoracic cavity. In humans, as in the other mammals, this is achieved primarily through the contraction of the diaphragm, but also by the contraction of the intercostal muscles which pull the rib cage upwards and outwards as shown in the diagrams on the right. During …
