as I was told from early education that the air we currently breathe in contains 21% oxygen and 77-ish% of nitrogen and the rest are other particles.
So I have a dumb question on what the body uses nitrogen we breathe in for?
In: 387
Nitrogen prevents the oxygen from being dangerous to the body. Oxygen likes to react with other substances especially if it’s not O₂. The limit we can survive is 1.7 Bar pressure, but even before that it does small damages.

Also it allows us (by not being CO₂) to get rid of the CO₂ we produce.
