If our body needs oxygen in the air to live. then what the 77% of nitrogen do to our body?

1.66K views

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?

Nothing. It just gets breathed straight back out.

Nitrogen gas comprised two nitrogen atoms bonded together and it is an extremely stable molecule. Our bodies have no way of braking it down, it needs something like a lightning strike or the conditions (temperature and pressure) found in an internal combustion engine or power plant to force the nitrogen to react with oxygen.
