A deep understanding of respiratory anatomy and physiology is fundamental for medical trainees, forming the backbone of effective diagnosis and management of respiratory conditions. From recognizing normal lung function to identifying pathophysiological changes in diseases like asthma, COPD, and respiratory failure, this knowledge is essential in both routine and critical care settings.
Khan Academy provides an introductory unit on respiratory anatomy and physiology in their Health and Medicine course, which is aimed for those first encountering this content. This can be a valuable refresher for major content topics, or to share with patients who may want to do some self-study. It includes some biophysics relevant to respiration.
Understanding Type 1 Respiratory Failure: A Clinical Primer
Dr. John B. West is a pioneering figure in respiratory physiology whose contributions have fundamentally shaped our understanding of lung function. His lectures on respiratory physiology are considered essential educational resources for medical students, residents, and practitioners worldwide.
This book, by Richard M. Schwartzstein and Michael J. Parker is now a free, open-access interactive web textbook. It takes a systems-based approach built around the controller, ventilatory pump, and gas exchanger, and covers lung mechanics, gas exchange, acid–base physiology, dyspnea, and exercise. The text is paired with animated, manipulable figures and review questions that link core physiology to bedside reasoning.

This webpage covers bronchoscopic and lymph node anatomy, featuring educational resources, diagrams, and a videobronchoscopy poster. It highlights the IASLC lymph node map for lung cancer staging and disease assessment, serving as a concise reference for medical professionals.
Ventilation and perfusion represent the two critical components of gas exchange in the lungs, where ventilation refers to the movement of air into and out of the lungs while perfusion describes the flow of blood through the pulmonary capillaries, with optimal respiratory function depending on the proper matching of these processes across different lung regions.
