A pulmonary alveolus (plural: alveoli, from Latin alveolus, "little cavity") is a hollow cup-shaped cavity found in the lung parenchyma where gas exchange takes place. The alveolar epithelium can be classified as a continuously renewing tissue since it comprises a population of cells (AE2) that are The time needed to replace all cells of a given population, termed cell turnover time, is quite variable and depends on the specific tissue, developmental stage or age...

The epithelium of the alveoli, contains two main types of cells: type I pneumocytes: large flattened cells - (95% of the total alveolar area) which present a very thin diffusion barrier for gases. type II pneumocytes (making up 5% of the total alveolar area, but 60% of cells). These cells secrete 'surfactant' which decreases the surface tension between the thin alveolar walls, and stops alveoli collapsing when you breathe out.
