"WebMost oxygen travels around the body in red blood cells. CO 2 is the catalyst that causes the red blood cells to release this load of oxygen to the body. If you breathe through an open mouth, you lose too much CO 2. So nose breathing enhances your body’s ability to access the oxygen in your blood. " - Oxygen receptors
