alveolus
Tiny lung pocket
An alveolus is a small cavity or sac in the body.
The term most often refers to the tiny air sacs in the lungs where oxygen and carbon dioxide exchange occurs: The alveoli give the lungs an enormous surface area for gas exchange.
It also names the bony socket holding a tooth.
Plural: alveoli.
