The Mouth Or nose take air. The mouth takes food because the nose only heads to the lungs and ears. Not the stomach. If you take food in your nose it is quite possible that you will get lung bacteria as all food has bacteria in it. The bacteria will breed with the lung formulas and create lung bacteria. That is if the food even makes it to your lungs. Which it wont I assure you it has about a 5 percent chance rate to get into your lungs more likely you would stop breathing before that. However if you breath through your mouth it connects to your lungs . Yet it also connects to you stomach. Anotamy is very complicated but I am very good at it. Hope this helped.
