I used to believe that air moved only in and out through the mouth when we breathe, and not the nose. When our mouths were closed, the air could squeeze through between our lips because the molecules of air are so small. My mom disproved this to me by having me hold my nose, close my mouth and then try to breathe. I was shocked!
