In the fetus, the ductus venosus shunts a significant majority (80%) of the blood flow of the umbilical vein directly to the inferior vena cava. Thus, it allows oxygenated blood from the placenta to bypass the liver. In conjunction with the other fetal shunts, the foramen ovale and ductus arteriosus, it plays a critical role in preferentially shunting oxygenated blood to the fetal brain.

What else can I help you with?
What structure serves as the lungs for a fetus?
The structure that allows blood to bypass a fetus inmmature liver is called ductus venosus.
What is the foremen ovale and the ductus venosus?
The foramen ovale is a hole in the heart that allows blood to bypass the lungs in a developing fetus. The ductus venosus is a blood vessel that connects the umbilical vein to the inferior vena cava, allowing oxygen-rich blood from the placenta to bypass the liver in a fetus.
What is the function of umbilical vein in fetus?
The function of the umbilical vein is to deliver oxygenated blood from the placenta to the fetus. From the placenta, the umbilical vein courses through the liver via the ductus venosus (fetal shunt), connecting then to the inferior vena cava.
What is the branch of the umbilical vein in the fetus that connects with the inferior vena cava bypassing the liver?
another fetal structure ?

What is the vessel that bypasses the liver?
The ductus venosus.
Formen ovale Ductus arteriosus Ductus venosus what will these shunts become in a newborn?
In a newborn, the foramen ovale will close and become the fossa ovalis. The ductus arteriosus will close and become the ligamentum arteriosum. The ductus venosus will close and become the ligamentum venosum.
What is the most fetal blood in the umbilical vein enters the inferior vena cava through?
The most fetal blood in the umbilical vein enters the inferior vena cava through the ductus venosus.
Fetal blood that passes through the ductus venosus is relatively High in oxygen and nutrients?
The ductus venosus shunts most of the left umbilical vein blood flow directly to the inferior vena cava. This allows relatively highly oxygenated blood from the placenta to bypass the liver and get to the fetal brain.
The shunt that allows most fetal blood to bypass the liver?
The Ductus Venosus
Why is the ductus venosus no longer needed when the pig born?
The ductus venosus is a fetal blood vessel that allows oxygenated blood from the placenta to bypass the liver and flow directly into the inferior vena cava, facilitating efficient circulation. Once a pig is born, it begins to breathe air, and its lungs expand, significantly increasing blood flow to them. This shift in circulation makes the ductus venosus unnecessary, as oxygenated blood can now be obtained directly from the lungs rather than the placenta. Consequently, the ductus venosus closes and eventually becomes a fibrous remnant in the adult pig.
