Answer:
Answer Key
Explanation:
Nitrogen is an inert gas with regard to inhalation / exhalation, that is, the body does not do anything with it. Any inert gas inhaled with X percent by volume will be exhaled with Y percent by volume, with X > Y, because we are exhaling more gas overall than we inhale.

because nitrogen is not exchanged ( across the alveolar epithelium) hence its concentration remains the same, the only gases that are exchanged during inhalation and exhalation are O2 and CO2
