Homework Help: Biology Question

Posted by Mary on Sunday, March 11, 2012 at 9:02pm.

I have 2 problems/questions I am unsure of the answers.
The first one is "how would you demonstrate the Valsalve maneuver using the model lung?"

and 2. If a woman is breathing rapidly and deeply after exercise, would TLC, RV, TV, IRV, and ERV stay the same, increase or decrease? Thank you for any help.
