FETAL CIRCULATION Special Structures in Fetal Circulation Placenta: where gas exchange takes place during fetal life. Umbilical arteries: Carry de-oxygenated blood from the fetus to placenta. 2 in number. Umbilical vein: Brings oxygenated blood coming from the placenta to the fetus. 1 in number. Foramen Ovale: connects the left and right atrium. It pushes/ shunts blood from the right atrium to the left atrium. Ductus Venosus: Carry oxygenated blood from umbilical vein to inferior vena cava, by passing fetal liver. Ductus Arteriosus: carry oxygenated blood from pulmonary artery to aorta, bypassing the fetal lungs. Flow Chart of Fetal Circulation Detail: The umbilical vein carrying the oxygentaed blood (80% saturated) from the placenta, enters the fetus at the umbilical and runs along the free margins of the falciform ligament of the liver. In the liver, it gives off branches to the left lobe of the liver and receives the deoxygentaed blood from the portal vein. The g
