taras22,
The word "tractate" was more of me making fun of myself for writing a simplified, albeit too long, answer to your question about V/Q mismatch and body movements. I cannot agree more that it was misdirected and a waste of time and electrons.
I do not mind learning so I learned about existence of the field of respirology. I will try to research more on that.to find out what exactly it would encompass. It may be my fault that I have never come across a respirology expert. For some reason, I constantly feel it must be something like pulmonology but, given the responses of your partner, I find it hard to believe. For now, I can only wholeheartedly recommend those two well-known books by Dr. John B. West to your respirology partner. I know she is surely very familiar with them, they are as basic as it gets, but we all need a simple refresher from time to time.
That all brought me to your earlier suggestion I speak to exercise physiology folks about control of breathing. Very simplified, but still interesting, thoughts may be found at 46:08...

If nothing else, it may be interesting for your partner to see how Dr. West, with whose work she is certainly well-acquainted, looks like.
