The Reason behind Different Zonal Distributions of Lung Diseases

Companion Anki Deck for this talk: https://ankiweb.net/shared/info/18254...

Armed with a basic understanding of pathophysiology and how well ventilation, blood perfusion, and lymphatic clearance work in different regions of the lungs, you can have a much better shot at remembering or making educated guesses about the geographic distributions of many lung diseases you’ll encounter.

Some of the case images in this talk appear courtesy of Ahmed El-Sherief, MD.
