Gives students a solid grasp of those aspects of pulmonary physiology that are essential for an understanding of clinical medicine. The Sixth Edition presents a new section of case presentations, improved illustrations, problem-based examples, and new study questions & answers after each chapter to help students prepare for the USMLE Step 1. With Michael Levitzky's clear and involving presentation of pulmonary physiology, you learn how and why the human respiratory system works-in a format that makes it easier to absorb and to integrate as you learn the physiology of other body systems.
