I'm a medical student who's just gotten through studying lung physiology and function in great depth. I'm also a cardio-pulmonary patient, so I have had years of teaching and information from my own doctors, along with my husband, who's a cardio-pulmonary physician, about lung physiology. You seem to have some challenges learning things from other people or trusting that they may know what they're talking about thanks to education. Fortunately, I do not. That's how I learned about lung physiology.

Someday you might want to do some reading about pulmonary physiology. You can confirm what I said above within the first 15 minutes or so.
