What organs have dual blood supply?
The brain is supplied blood from the left and right carotid arteries. If supply from one of the carotid arteries is cut off, the other can still supply enough oxygenated blood to keep the brain alive and functioning.
What is the sudden death of a brain cell when their blood supply is interrupted is called?
a stroke
Does blood flow to your head why?
The head and brain have a huge blood supply due to the fact that there is a very large metabolic demand going on in your brain! - It needs a lot of oxygen, nutrients, sugar and blood!
What is damage to the brain called in a medical context?
A stroke. A stroke is the rapidly developing loss of brain functions due to a disturbance in the blood vessels supplying blood to the brain. This can happen because of ischemia (lack of blood supply), or hemorrhage.In the past, stroke was referred to as cerebrovascular accident or CVA, but the term "stroke" is now preferred.
What is it called when blood stops reaching the brain?
When your heart stops beating, there is no blood getting to your brain. And so what happens is that within about 10 sec., brain activity ceases.When doctors shine a light into someone's pupil, it's to demonstrate that there is no reflex present. The eye reflex is mediated by the brain stem, and that's the area that keeps us alive; if that doesn't work, then that means that the brain itself isn't working.
Why are there blood vessels around the brain?
The blood vessels around the brain help supply energy for your brain

Why does the brain need a continuous supply of blood and oxygen?
The brain needs so much blood because it needs a constant supply of it to keep up with the neurons metabolic demands. 20 percent of the blood that comes from the heart is pumped directly to the brain.
Why is there a redundant blood supply to the brain?
There is a redundant blood supply to the brain to ensure uninterrupted oxygen and nutrient delivery, as the brain is highly sensitive to any disruption in blood flow. The redundancy comes from the two main arteries that supply the brain, the internal carotid arteries and the vertebral arteries, which can compensate for each other if one becomes compromised. This redundancy helps to minimize the risk of brain damage due to reduced blood flow.
What is the general definition of stroke?
A disturbance in the blood supply to the brain
