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
Nothing, so much so that if you take the nitrogen out of the air we breathe completely we’d still be fine. This is actually what they do in spacesuits, they are filled with pure oxygen at 4.3psi compared to normal atmospheric pressure of oxygen+nitrogen at 14.7psi. Having a low pressure in the suit like this means they’re not so inflated so easier to make them flexible to move around in (think the difference between a deflated and fully inflated football)
