How are alveoli specialised
Web3. Bronchioles lead to small bags called the alveoli. 4. The alveoli are where gas exchange happens. 5. Oxygen diffuses from alveoli into the blood. 6. Alveoli are 1 cell thick. 7. Alveoli have a rich supply of blood capillaries. 8. Alveoli have a large surface area because there are lots of them. 9. You breathe in oxygen rich air.
