Vedclass · Answer

(A) Nitrogen is the most abundant gas in the atmosphere, making up about $78\%$ of the air we inhale. Since the human body does not have any metabolic process to utilize nitrogen gas $(N_2)$, it does not participate in cellular respiration or any other biological function. Therefore, the nitrogen that enters the lungs during inhalation remains inert and is exhaled back into the atmosphere along with $CO_2$ and other gases during the process of exhalation.

When we breathe in air, nitrogen also goes inside along with oxygen. What is the fate of this nitrogen?
