What is physiological shunt?
Is a mixtures of oxygenated blood with some deoxygenated blood. It results in reduction of arterial PO2 by 2mmHg and reduction of arterial oxygen saturation by 0.5% compared to oxygenated blood coming from alveolar capillaries
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 shunted?
A conductor having low resistance in parallel with another device to divert a fraction of the current. It is sometimes called a Resistor. The causative diversion of venous blood into oxygenated arterial blood and thus mixing is also a shunt. "shunting"
What happens to the septum when it has a hole in it?
Some times the foramen ovale does not seal. Then you have blood flow from left atrium to right atrium. So there is more blood flow through the lungs. This may lead to pulmonary hypertension, with it's sequels.
What is the difference between a shunt and a stent?
A shunt is a passage between blood vessels which diverts blood. A stent is used to prop open an artery.

In atrial septum defect primum why the blood shunt from left to right atrium?
In the atrial defect primum, the blood shunt from the left to the right because of the blood volume overload from the right.
What is Vascular shunt?
Vascular Shunting is the distribution of blood to working muscles around the body.
What is a shunt resistor used for?
A shunt resistor is used to carry a majority of the electrical current away from the outlet. This causes the risks of electric shock to be down significantly, but still not completely gone.
What is the foremen ovale and the ductus venosus?
shunt blood in fetal circulation
What is shunt flow of blood?
along certain circulatory pathways such as the intestines there are points where small arteries have direct connections with veins. When these connections are open they act as shunts which allows blood in the artery to have direct access to a vein. These interconnections allow for sudden and major diversions of blood volume according to the physical needs of the body. The term shunting of blood: the brain changes the amount of blood flow going to certain places by changing the size of the arterioles.
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.
