Alveoli are part of the reparation system found in the lungs. They are covered in capillaries. In Alveoli, oxygen diffuses from the air into the blood vessels surrounding the alveoli and carbon dioxide from the body diffuses from blood into the alveoli’s air spaces. Alveoli clump together and form sacs.
