An alveolus is an anatomical structure that has the form of a hollow cavity and is found in the lung parenchyma ( tissue inside the lung). The pulmonary alveoli are the terminal ends of the respiratory tree that outcrop from either alveolar sacs or alveolar ducts; both are sites of gas exchange. The alveolar membrane is the gas-exchange surface.
