This compact, concise, easy-to-read monograph explains the key concepts and equations in respiratory physiology. The Seventh Edition updates and revises material to reflect current advances in respiratory science but does not stray from the proven formula students and faculty have enjoyed since 1974. New updates include physiology of pulmonary capillaries, hypoxic pulmonary vasoconstriction, pulmonary edema, surface tension, elastic properties of the lung and chest wall, metabolic functions of the lung, and perinatal respiration. Ample illustrations and pedagogical features help clarify important equations and concepts. USMLE-style review questions at the end of each chapter help students review for class or boards.
