Carbon dioxide is a waste material removed by the respiratory system through exhalation. It is a byproduct of cellular respiration and needs to be eliminated to maintain the body's proper pH balance.
Without a proper oxygen mask, a pilot's respiratory system can collapse in a supersonic plane.

The respiratory system supplies oxygen to the blood cells and removes waste gases from the blood cells. Carbon dioxide is the primary waste gas that is removed.
