Narrator: What's wrong with breathing through you mouth?

Jordan S. Josephson, MD: We're really not intended to breathe through our mouth, because as you breathe through your nose and it filters out all those particles in the mucus that you create, then those particles in the mucus gets dropped down into the back of your nose, into your throat and then you swallow it and then all of the bacteria and viruses and the pollution gets excreted through your digestive tract. That's why your sinuses and your airway are connected to your digestive tract. It's really one aero digestive tract, is the term that we use. Aero, meaning airway, digestive meaning digestion, and that tract is really one tract that helps you to filter the air that you breathe.
