•The alveoli are tiny air sacs within the lungs where the exchange of oxygen and carbon dioxide takes place.

Explanation:

The bronchioles lead to grape-like clusters of microscopic sacs called alveoli. In each adult lung, there are about 300 million of these tiny alveoli. A thin membrane makes up the alveoli sacs. Oxygen and carbon dioxide pass through this membrane to and from capillaries.
