What happens to the veins or arteries in the umbilical cord that were connected to the baby (the baby's end)?

In brief: Not needed any more!

The two arteries and vein that are in the cord, as well as the supporting gelatinous-like substance that surrounds those vessels, pretty much just 'shrivel up'.
(in the womb, they carried blood to and from the placenta.) it isn't unusual to see a very small amount of blood as the dried stump of the cord separates, and even a few days after that, but there shouldn't be any other kind of discharge.

In brief: Shrink/dry/fade

These structures are actually still functional for a time after birth if needed.
Babies in the NICU may have their fluids given/blood pressure monitored through one of the arteries, or get fluids thru the vein. After the blood flow stops, these spasm, dry out and eventually collapse on themselves. The babies body retains the remnants for a while but it disappears over time.
