Explanation:
Detailed explanation-1: -The ductus venosus branches from the left umbilical vein and acts as a shunt allowing freshly oxygenated blood to bypass the fetal liver and flow directly into inferior vena cava.
Detailed explanation-2: -Oxygen and nutrients from the mother’s blood are transferred across the placenta to the fetus through the umbilical cord. This enriched blood flows through the umbilical vein toward the baby’s liver. There it moves through a shunt called the ductus venosus. This allows some of the blood to go to the liver.
