Expiration and inhalation
How are expiration and inhalation carried out?
Expert

Whenever the thorax volume is raised an internal pressure lower than the atmospheric pressure (or external) is made and gases naturally enter the lungs. Whenever the thorax volume is lowered, the internal pressure increases above the external pressure and the air is debarred from the lungs.
