The alveoli (singular, alveolus) are the functional units of the lungs of mammals.

The bronchioles terminate in a grape-like cluster of alveoli in the lungs.

The surfactant, also they have only one layer of squamous epithelial tissue, they have no mucus membranes, grape like cluster, one single thick cell.
These are called alveoli. The singular term is alveolus.
They are called alveoli
Gas exchange takes place inside the lungs in the alveoli. The alveoli are a "grape like" structure at the very end of the respiratory tract. The alveoli are composed of a very thin membrane that separates the blood vessels from the gas chambers. The thin membrane allows diffusion of oxygen into the blood stream and diffusion of carbon dioxide (CO2) out of the blood stream. Once the CO2 has diffused into the alveoli, it is exhaled.
