alveoli  Segmented 3D images of alveoli in ducts and sacs in inspiration and in expiration Scale bar, 50 μm The ratio of the alveolar depth The walls of alveoli are extremely thin and comprised primarily of simple squamous epithelium The thin simple squamous cells that form the majority of an

Pneumonia is an acute inflammatory response deep in the lungs, in the alveoli When a tissue is infected or injured, there is an inflammatory response that is, Pulmonary ventilation provides air to the alveoli for this gas exchange process At the respiratory membrane, where the alveolar and capillary walls meet, gases

Alveoli have moist walls that are only one cell thick which makes the exchange surface very thin and the process of diffusion much quicker  Alveoli allow oxygen to enter the blood They are very thin to let oxygen move from the lungs to the blood vessels, and for carbon dioxide to be
