Explanation:

The alveoli are clusters of small sacs at the end of the bronchiole tubes.

These sacs fill with air with each inhalation.

The alveoli are surrounded by capillary beds. Both the alveoli and the capillary walls are one cell thick and allows for the diffusion of Oxygen O2 and Carbon Dioxide CO2 between the lung tissue and the blood.
