==Expiration==
==Expiration==
During Expiration, the pressure within the [[Pleural cavity and membranes - Anatomy & Physiology|Pleural Cavity]] increases to greater than that of the external environment, in orfer to expel air from the lungs. This is achieved by decreasing the lung volume, caused by relaxation of Inspiratory Muscles:
During Expiration, the pressure within the [[Pleural cavity and membranes - Anatomy & Physiology|Pleural Cavity]] increases to greater than that of the external environment, in orfer to expel air from the lungs. This is achieved by decreasing the lung volume, caused by relaxation of Inspiratory Muscles:
**Dome of the Diaphragm is pushed back by the intrathoracic pressure.
**Dome of the [[Diaphragm - Anatomy & Physiology|Diaphragm]] is pushed back by the intrathoracic pressure.
**Ribs recoil back to their original position.
