'04 5.4L what are these vacuum lines for? One is broke, one is crumbling

2004 f150 supercrew lariat 4x4 5.4L. I was cleaning the throttle body today and found these 2 issues.

1. Goes from passenger side intake, behind the throttle body and hooks to something on the driver’s side, it is very crumbly and needs to be replaced.

2. This one is a tiny line on the drivers side, not sure what it is or where it goes, or perhaps its a vent of some sort?

...the small one looks like the vent line for the IWE (4x4).

First one is the Evaporative Emissions hose from the purge valve to the intake.
