The three early embryonic circulations
Three paired veins drain into the primordial heart tube: vitelline veins (returning poorly oxygenated blood from the yolk sac), umbilical veins (carrying well-oxygenated blood from the primordial placenta) and common cardinal veins (return poorly oxygenated blood from the body of the embryo).
The vitelline venous system gives rise to the liver sinusoids and portal system, and forms the ductus venosus which shunts blood from the umbilical vein to the IVC.
