Describe the flow of blood from the umbilical vein to the descending aorta in the developing fetus.
n200080 [17]

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.

A small amount of the blood continues on to the lungs. Most of this blood is shunted through the ductus arteriosus to the descending aorta. This blood then enters the umbilical arteries and flows into the placenta. The oxygen rich blood then returns to the fetus via the third vessel in the umbilical cord (umbilical vein). The oxygen rich blood that enters the fetus passes through the fetal liver and enters the right side of the heart.

Why do you think astronomers even classify dwarf planets? Why not just catalog planets and leave it at that?
olchik [2.2K]
This is my opinion- please note this is NOT a fact:

Scientists label planets and dwarf planets to further distinguish what actually classifies a planet. If scientists didn’t have a classification system, the argument could be made that solid matter in space could be named a “planet” (asteroids, moons, etc.). Having certain classification thresholds means that planets that could support life are identified.

Again- this is NOT fact, my simple opinion. I could be very wrong.
