The alveoli are adapted in three ways: Moist, Large surface area, Good blood supply. WebIt serves to funnel air to the lungs. The alveoli are the sites of gas exchange; they are located at the terminal regions of the lung and are attached to the respiratory bronchioles. The acinus is the structure in the lung where gas exchange occurs. The sac-like structure of the alveoli increases their surface area.
