Vitelline veinsThese are right and leftAfter development of the liver, the break downinto hepatic sinusoidsThe blood from the left side is rechanneled to theright side, after reduction of the left sinus horn,the right vitelline vein is enlarged and becomethe right hepatocardiac channel.The proximal part of the left vitelline veindisappearsDistally the right and left vitelline veinsanastomose around the duodenum, andeventually form the superior mesenteric vein.

The proximal parts of both right and leftumbilical veins disappear.The remainder of the right umbilical vein
disappears.The left umbilical vein becomes connectedto the liver sinusoids, but a directcommunication between the left umbilical
vein and the right hepatocardiac channelis established, that is ductus venosus,which is obliterated after birth and formligamentum venosum,

Anastomosis and shifting of bloodto the right
Anastomosis between the anteriorcardinal veins, forming the leftbrachiocephalic vein, The
communication with left commoncardinal is obliterated.Superior vena cava is formed in theright side by right common cardinaland proximal potion of right anteriorcardinal.
