Y1 - 2015 N1 - T2 - Fishman's Pulmonary Diseases and Disorders, 5e AB - This chapter and the two succeeding it together share responsibility for presenting the physiological basis of normal pulmonary gas exchange. Gas exchange occurs by an integrated series of gas transport steps between the environmental air we breathe and the Hb molecule of the red cells passing through the pulmonary capillaries. These transport steps are of two types—diffusive and convective, and a number of conceptually separate diffusive as well as convective processes interact to accomplish the gas exchange mission. This is true both for gases that are taken up from the environment into the blood (i.e., O2 and occasional toxic gases or volatile anesthetics) and for gases that are eliminated from the body (i.e., CO2 and volatile anesthetic agents).
