Pulmonary Gas Exchange

Overview
  • Gases in the alveoli must cross the alveolar membrane to enter the blood and be transported into tissues. We first discuss some basic concepts related to how gases can exist within mixtures, as occurs in atmospheric air, and how gases can exist within a liquid medium. Subsequently, we describe some some basic principles of gas transport across the alveolar membrane and then discuss specific features of oxygen and carbon dioxide gas exchange.
