Is there a limit to the amount of mucus that can be produced by a person and expelled through their nose? Where IS it all? And what determines how thick it is?

Do you know? I was going to research these incredibly intriguing questions and answer them right here(!) but then was too overwhelmed by the overly-scientific explanations that I found on Google. Anyone want to take a stab at the answer or part of it? Because that’d be cool. Do it in honor of Allergy Season!
