Postnatally, the umbilical vein becomes which ligament?

After birth, the umbilical vein degenerates into a fibrous cord within the liver called the ligamentum teres hepatis (round ligament of the liver). This remnant marks where the normal fetal vessel extended from the umbilicus to the liver, as the placental blood supply is lost and the hepatic circulation reorganizes. The other fetal shunts leave different remnants: the ductus venosus becomes the ligamentum venosum, the ductus arteriosus becomes the ligamentum arteriosum, and the foramen ovale leaves the fossa ovalis.
