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.

∙ 13y agoAbout 98% of blood that enters left atrium ) coming back from lungs has just passed through alveolar capillaries and is thus oxygenated (pressure is 104 mmHg). Another 2% of blood has passed from aorta through bronchial circulation (bronchial artery) for O2 supply of deep (lower half) tissues of lungs. This blood (2%) is not exposed to lung air, so this blood flow is called "shunt flow". Since it is deoxygenated blood and will meet up with oxygenated blood, it decreases the pressure or oxygen in the systemic areteries ( pressure is reduced to 95 mmhg)

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 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.
How does sweating cause heat loss?
Well, the skin arteriole is widened, the shunt vessel closed, and there is a rapid blood flow in the capillaries, which keeps it warm. Thereofre, the sweat gland opens up and causes secrtetion of the sweat, cooling us off.
What is the blood flow from kidney to diaphragm?
steps of blood flow from heart to kidney
What structure in the dermis help maintain the temperature?
Firstly, your sweat pores help maintain temperature by opening or closing. When your body temperature is too high, the sweat pores open and more sweat is released outside of your body, thus resulting in more evaporation of sweat and a faster cooling of your body. When your body temperature is too low, your sweat pores close and sweat production decreases to minimize heat loss. Secondly, your skin arterioles and shunt vessels help maintain your body temperature by dilation or constriction. When your body temperature is too high, your shunt vessels constrict and your skin arterioles dilate, thus causing less blood to flow into the shunt vessels and more blood to flow into the blood vessels nearer your skin and losing heat more efficiently. When your body temperature is too low, your shunt vessels dilate and your skin arterioles constrict thus causing more blood to flow into the shunt vessels and less blood to flow into the blood vessels nearer your skin and thus minimizing heat loss. Hope that helps!
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.

What is Vascular shunt?
Vascular Shunting is the distribution of blood to working muscles around the body.
What is the medical term meaning abnormal blood vessel creating abnormal blood flow around the liver?
The answer is Protosystemis ShuntOrdinarily the blood coming away from the digestive tract is kept in a venous network (the "portal" system) separated from from blood that is returning directly to the heart via the vena cava (the "systemic" flow). This portal blood must first be cleaned and detoxified by the liver before merging with systemic venous blood.If there is abnormal flow which permits the "dirty" digestive blood tobypass the liver, it is called a Porto-Systemic "shunt".
What is the foremen ovale and the ductus venosus?
shunt blood in fetal circulation
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.
The shunt that allows most fetal blood to bypass the liver?
The Ductus Venosus
What is the blood flow in the body?
