* Arise from Iliac arteries along with vesicular arteries to the bladder.

=== Umbilical Veins ===

* Form the ventral ligament of the bladder in the adult.

A single umbilical veins runs from the fetus and joins the '''hepatic portal vein''', effectively circumventing the liver which is not yet fully patent. The umbilical vein transports oxygen-rich and nutrient-rich blood from the placenta to the fetus.
