Alveolar means pertaining the the alveolus (plural alveoli), the small air sacs in the lungs.
The air spaces in the lungs are called pulmonary alveoli. They are where gas exchange occurs in the lungs of mammals.
The actual air exchange in the lungs takes place in the alveoli, which are tiny sacs at the end of the bronchioles. Oxygen from the inhaled air passes through the walls of the alveoli and into the bloodstream, while carbon dioxide moves from the blood into the alveoli to be exhaled.
There are many capillaries in the lungs. These small blood vessels are the site of gas exchange in the alveoli.
