How are lungs adapted for gas exchange bbc
WebAlveoli are highly adapted for gas exchange by diffusion between air in the lungs, and blood in the capillaries. They are folded in order to maximise the surface area to volume ratio. This allows more gas exchange to take place. The alveoli wall linings are moist, allowing oxygen and carbon dioxide to dissolve easily.
