Default How does the AIR/smog system work

Looking at the smog system on my 81 , how the heck does it work. I see a metal tube that goes to the converter, where is it coming from? Seems that having the exhaust gases going through the converter would be enough.. Just trying to figure out how it all does its job

In a nutshell, the AIR system pumps air into the hot exhaust gases to burn additional hydrocarbons.

Looks like the lines come from the exhaust manifolds too? Is also coming from the carburetor as well?
