Prenatal and postnatal circulationĀ
Prenatal circulation Oxygenated blood reaches the fetus from the placenta via the umbilical vein (within the umbilical cord). Once in the fetus, the umbilical vein reaches the liver by passing through the falciform ligament. Much of this blood bypasses the liver through the ductus venosus. Oxygenated blood enters the right atrium through the inferior vena […]
