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
Air is made of many gases, but the most abundant of them is nitrogen.
Like many have pointed out, nitrogen is an inerts gas, meaning it does not react very easily with everything.
This makes it very useful for us, because when we breath air, all that mixture fills our lungs, but the lungs only take the oxygen. This is because oxygen can float freely in the nitrogen.
When oxygen touches our lung walls, then it gets absorbed.
Nitrogen can also carry out gases we don’t need like CO2.
It acts as a carrier vessel for oxygen we need and takes out gases we don’t need like CO2.
