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?

Like it does for most things, nitrogen does absolutely nothing.
It’s regarded as being inert for a reason. It doesn’t really interact with anything that isn’t a plant root.
The body takes in a volume of “air” (a composition of some dozen-or-so gasses at any one time.), takes some of the oxygen out of the 19-22% oxygen present in said volume (not even 1% of this present oxygen btw.) And then dumps it all out at once.
The reason some gasses, like H2S or CO are so deadly, is because our lungs can’t see the difference between it and oxygen. Both bind to blood cells like oxygen is supposed to, and are carried out through the body.
Think of it like ordering clothes as a man, then when your delivery arrives, it’s actually women’s clothes. “I can’t use this!” You might scream. You get mad, ask for a refund. Cells in your body are sort of like this, with the delivery man being your red blood cells. The only difference is that your body’s cells get so angry over this mixup that they literally just die.
