Function of the Mouth

1. Nasal Breathing. Nasal (Nose) Breathing, the first system, depends
   upon a well-grown upper palate or maxillae and palatine bones. Our
   oropharynx is important because nasal breathing actually ionizes the
   air we breathe. The paranasal sinuses also add nitric oxide to our air as
   it passes to our lungs, which helps with our heart and our metabolism.
   Most of our breathing should be via the nose for this reason as well as
   their conditioning and the cleansing effect of nasal reaching.


2. Mouth Breathing is an alternative to nasal breathing. We are not
   supposed to mouth breath all the time.


3. Suckling for Breastfeeding


4. Swallowing lubricates our digestive tract and allows us to consume
   food


5. Tongue-Powered Speech. Production of different speech sounds
   depends upon our all-powerful Tongue, which is powered by all five
   developmental nerves
