| extra-hepatic portion of the fetal left umbilical vein | ligamentum teres hepatis (the "round ligament of the liver"). |
| intra-hepatic portion of the fetal left umbilical vein (the ductus venosus) | ligamentum venosum |
| distal portions of the fetal left and right umbilical arteries | medial umbilical ligaments |
