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

1.21K 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?

The nitrogen’s just there to hold everything. If you think of a pool crowded with toys- the oxygen and carbon dioxide would be the toys and the nitrogen would be the water that holds them up so you can use them.
