When you breathe, air can flow through both the mouth and the nose, but it is possible to breathe only through your mouth or your nose!
You can also stop airflow through the mouth using a Bilabial Stop (lips pressed together), a Palatal Stop (tongue pressed to the hard palate), or even a Uvular Stop (tongue pressed against the uvular – like snoring).
The Nasopharyngeal Stop blocks airflow to the nose. This happens when you breathe only through your mouth. The uvula (represented by the circle) presses against the throat (represented by the vertical line).
The Velar Stop is between the Soft Palate (represented by the wiggly line) and the Tongue (represented by the curved line) being pressed together.
The Nasopharyngeal Stop is when the Uvula (circle) is pressed against the Throat (vertical line).
When you hold your breath with your mouth open you are preventing air flowing through the mouth using a Velar Stop and preventing air from flowing through your nose using a Nasopharyngeal Stop.
