And to prevent that from happening and to create a quick and efficient circulatory system of that fetus, what the fetus does is it redirects blood away from those two organs via special type of pathogeways, special types of Shuns known as the ductus arteriosis, the ductus venosis and the Forayman O'Valley. So remember, it's inside the placenta where gas exchange and nutrient exchange takes place. And as soon as that takes place, the oxygenated and nutrient filled blood will travel away from the placentum and towards this general direction via the umbilical vein. And eventually, when it approaches the liver, there will be a Shunt that will exist between the umbilical vein and the inferior venocave. And the Shunt is shown right here. It's known as the ductus venosis.
