Simple squamous epithelium of alveolus
An alveolus consists of an epithelial layer of simple squamous epithelium (very thin, flattened cells), and an extracellular matrix surrounded by capillaries. The epithelial lining is part of the alveolar membrane, also known as the respiratory membrane, that allows the exchange of gases. Visa mer A pulmonary alveolus (plural: alveoli, from Latin alveolus, "little cavity"), also known as an air sac or air space, is one of millions of hollow, distensible cup-shaped cavities in the lungs where pulmonary gas exchange takes place.

Simple squamous epithelia can form in the pericardial, pleural, and peritoneal cavities, as well as in areas where passive diffusion occurs, such as the kidney or alveoli in the respiratory tract. In simple epithelial cell culture, there is only a single layer of cells in the cell.
