venosus

The third structure that's important that connects the umbilical vein to the fetal circulation is a site, a junction, called the ductus venosus.

As soon as the cord is clamped, the ductus venosus ceases to carry blood to the heart, and it begins to constrict within the first few hours or days of life.

There was a reversal of end-diastolic blood flow seen in the ductus venosus and umbilical artery and pulsatile flow seen in the umbilical vein.

He observed, too, the canal which passes in the fœtus between the umbilical vein and vena cava, and which has since been known as the _ductus venosus_.

Ultimately the left vena revehens no longer communicates directly with the sinus venosus, but opens into the right vena revehens.

—The visceral veins are the two vitelline or omphalomesenteric veins bringing the blood from the yolk-sac, and the two umbilical veins returning the blood from the placenta; these four veins open close together into the sinus venosus.

—The first indication of a parietal system consists in the appearance of two short transverse veins, the ducts of Cuvier, which open, one on either side, into the sinus venosus.

The separation of the auricula from the sinus venarum is indicated externally by a groove, the terminal sulcus, which extends from the front of the superior vena cava to the front of the inferior vena cava, and represents the line of union of the sinus venosus of the embryo with the primitive atrium.

The sinus venosus is at first situated in the septum transversum (a layer of mesoderm in which the liver and the central tendon of the diaphragm are developed) behind the primitive atrium, and is formed by the union of the vitelline veins.
