Alveoli, (from Latin alveoli, "little cavities") are an anatomical structure which have the form of hollow cavities. Found in the lung, the pulmonary alveoli are spherical extensions of the respiratory bronchioles (small air passages leading off the windpipe) and are the primary sites of gas exchange with the blood. Alveoli are only found in the lungs of mammals.
