Encyclopedia : D : DU : DUC : Ductus venosus


Fetal circulation. The ductus venosus (red) connects the umbilical vein to the inferior vena cava. |- style="text-align: center;" class="hiddenStructure" | colspan="2" |

It is a shunt that allows oxygenated blood from the placenta to bypass the liver and return to the systemic circulation for distribution to the rest of the body.
