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) |
