The internal structure of the alveoli consists of thin walls made up of a single layer of epithelial cells, primarily type I pneumocytes, which facilitate gas exchange. These walls are surrounded by a network of capillaries, allowing oxygen and carbon dioxide to diffuse between the air in the alveoli and the blood. Additionally, type II pneumocytes produce surfactant, a substance that reduces surface tension and prevents the alveoli from collapsing. The alveolar structure is highly specialized to maximize surface area for efficient gas exchange.

The structure in the lungs that contains the thinnest epithelium is the alveoli. Alveoli are air sacs where the exchange of gases takes place.
