Ventilation Purpose Oxygen Consumed Cellular Respiration  Produced Waste

Ventilation maintains the oxygen and carbon dioxide concentration gradient in the alveoli to support cellular respiration.

Ventilation's purpose is to maintain the concentration gradient in the alveoli, ensuring a high concentration of oxygen for cellular respiration and a low concentration of carbon dioxide, which is a waste product.

Front purpose of ventilation
Back oxygen is consumed during cellular respiration, CO2 produced as waste product, so ventilation maintains alveoli concentration gradient (high O2, low CO2)
