What are the foramen ovale and ligamentum arteriosum?
A foramen ovale is both a hole in the skull through which nerves pass and a fetal shunt between chambers of the heart. The ligamentum arteriosum is the connective tissue between the pulmonary artery and the aortic arch and is a closed vestige of a fetal duct known as the ductus arteriosus.
What is the remnant of the foramen ovale?
The open gap which connects the left and right atria of the heart in a fetus. The fetus' pulmonary artery isn't used as it doesn't breathe in air and so when blood is pumped around it's heart it bypasses the pulmonary artery which would normally pump blood to the lungs.
Would a hole in the septum of the heart create a problem for an individual?
Yes, it would, as deoxygenated and oxygenated blood would mix. This is normally open in a foetus as the foramen ovale, which is a shunt between the left and right atrium, hence bypassing the pulmonary circuit as the foetus does not use its lungs to breathe. This normally closes in the first year of life.
What fetal shunt bypasses the lungs by directly connecting the right atrium and the left atrium?
In the fetal heart, the foramen ovale (or ostium secundum of Born) allows blood to enter the left atrium from the right atrium. It is one of two shunts, the other being the ductus arteriosus, that allows blood entering the right atrium to bypass the pulmonary circulation. Another similar adaptation in the fetus is the ductus venosus. In most individuals, the foramen ovale (pronounced /fɒˈreɪmən oʊˈvɑːli/) closes at birth. It later forms the fossa ovalis.

What heart disease causes cyanosis?
Is result of emberoylic defect that lead of right to left shunt
What does the ductus arteriosus shunt blood away from?
It is present to shunt leftover blood from the pulmonary artery to the aorta because the pressure in the right fetal heart is higher than that in the left.
There was machinery-like murmur of the heart and the doctors said that the connection between the aorta and pulmonary artery is still openWhat structure is this?
This is called a patent ductus arteriosus. "Patent" means it's still open. Ductus arteriosus is a shunt between the pulmonary artery and the aorta. The ductus arteriosus normally closes at birth or shortly thereafter. If it remains open, it constitutes a left-to-right shunt, meaning oxygenated blood enters the pulmonary circuit. It is critical that this shunt remain open in utero, as this is how fetal blood bypasses the lungs and enters the systemic circuit. After birth, however, the fetus must use the lungs to breath, and the ductus should close.
Which is a shunt that exists between the pulmonary and aortic trunks in the fetus?
The ductus arteriosus is a shunt between the pulmonary and aortic trunks in the fetus. This shunt normally is closed at birth.

Is tetrology of fallot a cardiovascular disorder?
Yes it is. A congenital malformation to be precise consisting ofPulmonary Stenosis: obstruction of the pulmonary outflow from the right ventricle;Narrowed pulmonary valveVentricular Septal Defect (VSD): There is a shunt in between the ventricles; a hole on the septum so to speak.Dextroposition of the Aorta with septaloverride: basically the aorta is displacedRight Ventricular Hypertrophy: thickening of the Right Ventricular Wall
Does the ductus ateriosus serve as a shunt?
Does the ductus ateriosus serve as a shunt in a fetal pig?
What happens when pulmonary vein and artery connect?
This is called a shunt. One that occur between the Pulmonary artery and the Pulmonary vein, would be a left to right shunt. So what would happen? The blood from the Pulmonary vein (having the high pressure) would enter the Pulmonary artery. The results would be that the blood just goes back to the lung for another cycle with be deoxygenated.

The shunt that allows most fetal blood to bypass the liver?
The Ductus Venosus
Why is circulation to the lungs bypassed in fetal pigs?
It is bypassed because there is no need for the blood to go to the lungs and get "pick up" if the pig is dead.
