Answer:
Ventilation (Pulmonary) AKA Breathing
Explanation:
Pulmonary ventilation is often known as breathing. It is the means through which air moving into the lungs in the course of inspiration (inhalation) and away from the lungs at expiration (exhalation). Air flows as a result of variations in pressure between the atmosphere and the gases within the lungs.
Air, just like gases, moves from a zone of larger pressure to a zone of smaller pressure. Muscular breathing activities and recoil of elastic tissues forms the variations in pressure that causes ventilation. Pulmonary ventilation employs three seperate or distinct pressures:
-Atmospheric pressure
-Intraalveolar (intrapulmonary) pressure
-Intrapleural pressure
-Atmospheric pressure is the air pressure that is not from within but from outside of the body.
-Intraalveolar pressure is the pressure within the lungs alveoli.
-Intrapleural pressure is the pressure present in the pleural cavity.
These three pressures are important for pulmonary ventilation.
