And so we have an exchange taking place. Oxygen and nutrients are picked up by the blood of that fetus, while carbon dioxide and other waste products are deposited into the blood of that mother. And once this exchange takes place inside the placenta, a special type of blood vessel carries the oxygenated and nutrient filled blood away from the placenta and towards the heart of that developing fetus. And this blood vessel is known as dambilical vein. So just like any vein always carries blood to the heart, umbilical vein always carries blood to that heart. Now, as dambilical vein shown in red, actually carries the oxygenated and nutrient filled blood to the heart, eventually it comes in close proximity with the liver, and there is a tiny blood vessel that goes into that liver.
