Simple squamous epithelium of alveolus
WebbAs a simple type of epithelium, simple squamous epithelium is one cell-layer thick, and thus every cell of the tissue comes in direct contact with the basement membrane. As with other types of epithelia, simple squamous epithelial cells are bound together by tight junctions, forming a selective barrier, which is crucial to its function. 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.
