The ligamentum teres is the remnant of which fetal vessel?

After birth, the vessels that carried blood from the placenta leave fibrous remnants in the abdomen. The ligamentum teres hepatis is the fibrous remnant of the umbilical vein, which in fetal life shuttled oxygenated blood from the placenta to the fetus and connected to the liver. As circulation changes after birth, this vein closes and becomes a cord within the falciform ligament—the ligamentum teres. Other fetal vessels form different ligaments: the ductus venosus becomes the ligamentum venosum in the liver; the ductus arteriosus becomes the ligamentum arteriosum; and the umbilical arteries become the median umbilical ligaments.
