: 21. What does the obliterated umbilical artery represent in the fetus?
One half of the umbilical artery (which was once a “paired artery”, one for each side of the body) - would take low oxygen blood from the fetus to the placenta, to the umbilical cord, to the mother. The non-obliterated umbilical artery remains active in the adult (branch of the interior iliac artery). - source: Wikipedia.
