Question

Quizplus · Accepted Answer

Ventilation is the movement of the respiratory medium (such as air or water) past the respiratory surface, which allows for the exchange of oxygen and carbon dioxide. This process occurs in organisms with respiratory surfaces, such as lungs or gills, and is necessary for proper gas exchange in aerobic respiration. The other options, while related to respiration, do not accurately describe the process of ventilation.
