Fetal Ductus Venosus
Cartoon showing the position and function significance of the ductus venous to fetal circulation.
Fetal blood is returned from the placenta to the fetus by the placental or umbilical vein.
- Placental vein enters the abdomen at the umbilicus, and passes upward along the free margin of the falciform ligament of the liver to the under surface of that organ, where it gives off two or three branches:
- 1 large to the left lobe.
- 1-2 smaller to the lobus quadratus and lobus caudatus.
- Placental vein at the porta hepatis (transverse fissure of the liver) divides into two branches:
- the larger is joined by the portal vein and enters the right lobe
- the smaller ductus venosus continues upward and joins the inferior vena cava.
