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
The 77% oxygen in the air is what prevents the oxygen from burning you alive.
Also the air is made from two nitrogen atoms which are triple bonded, this makes them extremely difficult to break apart and they don’t really serve a biological function in the human body, think of them as a buffer gas
