What are air sacs in the lungs also called?

Answer 1

There should never be "air bubbles" in the lungs. This would be an abnormal finding AND a life and death emergency. An air bubble that travels in the blood stream to the heart, lungs, or brain is an air embolism.

IF however you mean the sacs in the lungs that exchange (through the hemoglobin on red blood cells) carbon dioxide for oxygen, those grape-like structures are called aveoli. Aveoli are NOT "air bubbles" though. Numerous small blood vessels cover the outside of each aveoli. The Hgb releases oxygen to the aveoli; the aveoli then pass carbon dioxide back to the Hgb. The Hgb on the red blood cells cannot pick up the O2, until the Hgb lets go of the CO2. Because the aveoli are round and there are many of them, they have high surface area. One breath supplies enough O2 while exhaling the CO2.
