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.
