Alveolar Ventilation

Alveolar ventilation is the process by which fresh air reaches the alveoli—the tiny air sacs in the lungs where oxygen is exchanged for carbon dioxide in the blood. It depends on both the amount of air inhaled and the efficiency of gas exchange. Proper alveolar ventilation ensures that oxygen enters the bloodstream and carbon dioxide is removed effectively, supporting normal breathing and vital functions. Factors like breathing rate and volume influence this process, and issues such as lung diseases can impair alveolar ventilation, reducing oxygen supply and waste removal.
