WebFeatures of the alveoli. The average human adult has around 480 - 500 million alveoli in their lungs. This equals a surface area of 40 - 75 m 2. The large number of alveoli increases the surface area available for oxygen and carbon dioxide to diffuse across. The walls of the alveoli are only one cell thick and these cells are flattened. 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. philly airport belt f
