The alveoli is where the oxygen is exchanged in the blood. The reason they are in clusters is to maximize surface area. With emphysema the clusters are flattened and clogged with the tar from the cigarettes which is why they have such a hard time breathing.
The alveoli (singular, alveolus) are the functional units of the lungs of mammals.
"Alveoli"
The bronchioles terminate in a grape-like cluster of alveoli in the lungs.
function of type 2 alveoli cells is to secrete surfactant.
Alveoli are found within the lungs. The alveoli act as a specialised gaseous exchange surface in mammals. Another function of alveoli is the production of surfactant.
The bronchioles terminate in a grape-like cluster of respiratory structures called the alveoli.

The bronchi are the tubes that actually carry the air to the lungs, they have a different function than the alveoli which function in the process for gas exchange.
