"WebJun 6, 2024 · How does alveoli increase the surface area? Alveoli are lined by a fluid layer known as a surfactant which maintains the shape and surface tension of the air sac. By maintaining surface tension , there is more surface area through which oxygen and CO2 molecules can pass. How does air reach the alveoli? From the bronchi, air passes into … " - How do alveoli increase surface area

How do alveoli increase surface area

WebAlthough the surface tension of surfactant decreases with surface area compression and increases with surface area expansion, the surface area of an alveolus changes little with tidal breathing. The low surface tensions resulting from surfactant help to prevent alveolar collapse and keep interstitial fluid from flooding the alveoli.
