Alla [95]2 years ago

  • Each alveolus is cup-shaped with very thin walls.
  • It’s surrounded by networks of blood vessels called capillaries that also have thin walls.
  • The oxygen you breathe in diffuses through the alveoli and the capillaries into the blood.
  • The carbon dioxide you breathe out is diffused from the capillaries to the alveoli, up the bronchial tree and out your mouth.
  • The alveoli are just one cell in thickness, which allows the gas exchange of respiration to take place rapidly.
