WebThe exchange of oxygen and carbon dioxide occurs between the alveoli and the capillaries in the lungs Oxygen and carbon dioxide are exchanged in a process of simple diffusion; (passive movement from high to low concentration) The air in the alveoli contains a high concentration of oxygen. 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.
