Generally, nothing. Nitrogen (gas) is inert & cannot be used by any animals. The only organisms that can use gaseous nitrogen are the "nitrogen-fixing" bacteria. You breath in nitrogen, then breath it out. (I meant nitrogen is relatively inert)

I'm not sure it's true that nitrogen is inert, in the way other gases such as argon are inert - nitrogen can combine with oxygen and other elements in different circumstances to make new compounds. But the body has no use for nitrogen in gaseous form, and it's still true to say that we breath out what we breath in. We subject it to no chemical reaction in the way we do to oxygen.
