Pulmonary ventilation is the mechanical process of moving air into and out of the lungs, that is, it’s the process by which gas is transported from the air to the pulmonary alveoli and vice versa.

Pulmonary ventilation is based on the alternation between inspiration and expiration.

  • In normal conditions, inspiration is active, involuntary, carried out thanks to the participation of the respiratory muscles, mainly the diaphragm.

  • Expiration is a passive process, however, actions such as blowing, coughing, singing require the action of the expiratory muscles, which are the abdominals.

The objective of pulmonary ventilation is to transport oxygen to the alveolar space so that gas exchange takes place, that is, oxygen enters the body and carbon dioxide is eliminated.

Therefore, we can conclude that pulmonary ventilation consists of the inspiration or entry of air into the alveoli, the air actively enters the lungs as the rib cage dilates; expiration, or air release, is done passively.
