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 is Vascular shunt?
A vascular shunt is a temporary connection between blood vessels created to bypass a blocked or injured vessel. It allows blood to flow from one area to another, maintaining circulation until further treatment can be provided. Vascular shunts are commonly used in trauma patients to prevent tissue damage due to restricted blood flow.
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 shunting blood so that it may be filtered?
Shunting blood means redirecting it away from normal circulation to be filtered. In medicine, this process is often done using a shunt or specialized catheter to divert blood flow to an artificial filter or dialysis machine for purification.
Describe the physiological role and mechanism of extrinsic regulation of GFR?
Extrinsic regulation of glomerular filtration rate (GFR) involves factors outside the kidney that influence renal blood flow and GFR. For example, the sympathetic nervous system can constrict renal blood vessels, reducing GFR to shunt blood to other organs during fight or flight responses. Hormones like angiotensin II and natriuretic peptides also regulate GFR by altering renal blood flow and tubular reabsorption.
What does the process of blood flow with your body called?
blood flow is called circulation

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 the atrial defect primum, the blood shunt from the left to the right because of the blood volume overload from the right.
What happens during a peripheral shunt procedure?
A peripheral shunt procedure involves creating a connection between two blood vessels to reroute blood flow, typically to alleviate arterial blockages or improve circulation. This is commonly performed in patients with conditions like peripheral artery disease. Surgeons may use a graft or a synthetic tube to establish the shunt, ensuring that blood can bypass the obstructed area. The procedure aims to enhance blood supply to the affected limbs, reducing pain and improving overall function.
Why is a shunt put in for leg angioplasty?
A shunt is used during leg angioplasty to maintain blood flow to the affected area while the procedure is being performed. It helps to temporarily bypass the narrowed or blocked artery, ensuring that blood continues to circulate to the tissues. This is crucial for preventing ischemia and potential tissue damage during the intervention. Additionally, the shunt allows for better visualization and access to the area being treated.
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 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".
The shunt that allows most fetal blood to bypass the liver?
The Ductus Venosus
Why HMP shunt called as shunt?
The HMP shunt, or Hexose Monophosphate shunt, is referred to as a "shunt" because it diverts glucose-6-phosphate from the glycolytic pathway to generate NADPH and ribose-5-phosphate. This pathway provides essential reducing power for biosynthetic reactions and helps in maintaining cellular redox balance. The term "shunt" highlights its role in redirecting metabolic flow away from energy production towards biosynthetic and antioxidant functions.
Contraindication for taking blood pressure in right arm?
When there's a port or shunt in the arm blood pressure is contraindicated on that arm.
What is the medical term meaning redirection of the flow of body fluid from one cavity or vessel to another?
Shunt
