What would happen to the child if the umbilical umbilical vein ductus venosus ductus arteriosus and foramen ovale did not close?
foramen ovale is present in between the left and right arteries.so if that is not closed then the deoxygenated and oxygenated blood from the left and right arteries respectively will get mixed causing complications in respiration.soetimes this occurs in children known as blue baby syndrome.
What else can I help you with?
6 structures needed for fetal circulation?
Umbilical Arteries Placenta Umbilical Vein Ductus Venosus Foramen Ovale Ductus Arteriosus
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 function of the ductus venosus?
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.Source(s):http://en.wikipedia.org/wiki/Ductus_veno…

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 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.
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 fetal circulatory structure that carries blood with the lowest oxygen saturation?
The ductus venosus is the fetal circulatory structure that carries blood with the lowest oxygen saturation. It allows blood from the umbilical vein to bypass the liver and flow directly to the inferior vena cava.
Why is it important for the fetal heart to have both the ductus arteriosus and the foramen ovale but not good for the adult heart to have these?
The ductus arteriosus and foramen ovale are important for systemic circulation. This is the type of circulation maintained by fetal pigs but the adult heart requires pulmonary and systemic circulation.
Why is it important for the fetal heart to have both the ductus arteriosus and the foramen ovale but not good for the adult heart to have these feature?
The ductus arteriosus and foramen ovale are important for systemic circulation. This is the type of circulation maintained by fetal pigs but the adult heart requires pulmonary and systemic circulation.
What is the fate of the ductus arteriosus?
The ductus arteriousus connects the pulmonary artery with the descending thoracic aorta, allowing the blood to enter into the fetal circulation without going through the lungs. This structure closes at birth and becomes the "ligamentum arteriosus."
Blood from the umbilical vein enters the inferior vena cava through a bypass vessel in the liver is known as?
ductus venosus
