Answer 1

Answer:

Alveoli are tiny air sacs in your lungs that take up the oxygen you breathe in and keep your body going. Although they're microscopic, alveoli are the workhorses of your respiratory system. ... When you breathe in, the alveoli expand to take in oxygen. When you breathe out, the alveoli shrink to expel carbon dioxide.

Function: •moving air in and out of your lungs (ventilation)

•oxygen-carbon dioxide exchange (diffusion)

•pumping blood through your lungs (perfusion)
