Gaseous exchange
David C. Dugdale (2012)[1] defines gaseous exchange as the delivery of oxygen from the alveolar air space into the pulmonary capillaries and the elimination of carbon dioxide from the capillaries to the lungs. Both processes occur via diffusion, from a high concentraion to a low concentration. Capillaries are located in the walls of the alveoli and are only one cell thick, making them well adapted for gaseous exchange.
