The CO2 is diffused back into the alveoli, where, by the diaphragm, is pushed back into the environment by atmospheric pressure.

Tiny blood vessels or capillaries surround every air sac in the lungs. The blood vessels surround the aveoli like a net and the oxygen enters blood and the carbon dioxide is the let out.

It is released from the red blood cells in exchange for oxygen. The CO2 then is left in the alveolar sac to be expelled with the next breath.

Why do blood capillaries surround alveoli?

The alveoli are the sites of respiration: the oxygen in them provided by the inhaled air diffuses into the blood cells that flow through the capillaries. Carbon dioxide diffuses out of the blood and into the alveoli so it can be exhaled. The capillaries provide a way for the blood to reach the alveoli. Hope this helps
