Web27 de mar. de 2024 · Simply so, what are the adaptations of alveoli for gas exchange? 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.

Alveoli are adapted for gas exchange because they … WebWith this in mind, you can see how the alveoli are well adapted for fast diffusion/gas exchange: There are many many alveoli (around 500 million!)- meaning there is a large surface area for diffusion to occur. The alveoli walls (or alveoli epithelium) are one cell thick - therefore there is a short diffusion pathway (short distance).
