The remnant of the umbilical vein becomes a fibrous cord that runs in the free edge of the falciform ligament, known as the ligamentum teres (round ligament) of the liver. After birth, the umbilical vein loses its function as blood no longer travels from the placenta, so it fibroses and remains as this small, cord-like structure extending from the umbilicus to the liver. This is why ligamentum teres is the correct remnant question focus. The falciform ligament is simply the peritoneal fold that contains this cord and helps anchor the liver to the anterior abdominal wall, while the hepatic artery is part of the liver’s arterial supply and not a remnant of fetal circulation.
