Web26 aug. 2024 · Adaptations of the alveoli: Thin walls – alveolar walls are one cell thick providing gases with a short diffusion distance. Moist walls – gases dissolve in the moisture helping them to pass across the gas exchange surface. Permeable walls – allow gases to pass through. Carbon dioxide diffuses in the opposite direction. WebHow are the alveoli adapted to its function? - each alveolus is made from single layer of thin flat cells (alveolar epithelium) - this allows for faster rate of diffusion - oxygen diffuses out of alveolar space into blood - CO2 diffuses out from blood capillary into alveolar space - moist alveoli surface supports gas exchange
