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
Oxygen in high amounts is toxic. Our cells would be damaged from long exposure to high oxygen content.
Since nitrogen is not easily absorbed it keeps the air sacs (alveoli) in our lungs expanded for better gas exchange. This helps prevent collapse of the air sacs (atelactasis) and the bad things that come from that.
