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.

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?
The foramen ovale closes, becoming part of the interatrial septum. The Ductus arteriosus becomes the ligamentum arteriosum and the ductus venosus becomes 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.
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.
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."
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 most fetal blood in the umbilical vein enters the inferior vena cava through?
ductus venosus
Blood from the umbilical vein enters the inferior vena cava through a bypass vessel in the liver is known as?
ductus venosus
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 structure in the fetus that allows blood to bypass the lungs?
An valvular hole in the interatrial septum called the foramen ovale.
