All types of strokes involve a loss of blood flow to some part of the brain. Since the blood is supplying oxygen to the brain cells, the loss of blood flow results in a loss of oxygen to the affected area of the brain.
If the blood flow is not restored quickly, then the resulting loss of oxygen will cause that part of the brain to die.
Strokes can affect different parts of the brain and can have different causes.
Some examples of stroke types and their causes are:
1) Hemorrhagic Strokes are caused by bleeding within the brain cavity. Since the brain is surrounded by the skull, the extra blood can build up pressure on the brain and thus cut off normal blood flow.
2) Thrombotic Strokes are caused by a blood clot in an artery. The clot blocks the blood flow to the affected area of the brain.
There are other types of strokes from different causes, but in all cases there is a loss of blood flow to some part of the brain and a resulting loss of oxygen to the affected area of the brain.

What cells are affected if you have stroke?
It tends to be yyour brain that is affected by a stroke when it is starved of oxygen
Which cardiovascular problem results when a blood vessel in the brain becomes blocked or ruptures?
Stroke
What are the 2 different types of stroke?
There are two major kinds of stroke, ischemic and hemorrhagic. In an ischemic stroke a blood vessel becomes blocked, usually by a blood clot and a portion of the brain becomes deprived of oxygen and will stop functioning. A hemorrhagic stroke occurs when a blood vessel that carries oxygen and nutrients to the brain burst and spills blood into the brain. When this happens, a portion of the brain becomes deprived of oxygen and will stop functioning.

What artery is clogged if you have a stroke?
A stroke is when a clot causes a thrombus (blockage of flow of blood) in the veins of the brain. The brain has multiple arteries that supply it with oxygen.
What happen when a part of the brain does not get supply of oxygen and nutrients?
You are in danger of a stroke
How much of the body's oxygen does the brain need and what happens when it doesn't?
I don't know how much of the body's oxygen the brain needs, but when the brain does not receive enough, a stroke occurs.
Which disorder occurs when there is a loss of blood flow and in turn oxygen to the brain?
When there is a loss of blood flow and oxygen to the brain, it can lead to a condition called stroke. This can result in brain damage and various neurological symptoms depending on the area of the brain affected. Immediate medical attention is crucial to minimize the long-term effects of a stroke.
Results when brain region is deprived of blood or exposed to prolonged ischemia?
Stroke or Death
What doesn't receive oxygen during a stroke and dies?
During a stroke, brain cells do not receive enough oxygen and nutrients due to a blockage or rupture of blood vessels. This lack of oxygen causes the brain cells to die, leading to lasting damage or even death. Immediate medical attention is crucial to minimize the impact of a stroke.
Why does the blood leaving most organs in the brain have less oxygen than when it entered the brain?
The brain is generally considered one organ, and yes blood delivers oxygen to the brain, so when the blood leaves the brain, it is oxygen depleted. This oxygen fuels the brain through respiration, which gives it the energy to keep you alive and constantly keep your bodily functions in line. There is a blood brain barrier though, so blood never actually enters the brain and oxygen diffuses over this barrier.
When the blood supply to part of the brain is suddenly shut off?
Depending on the duration of the lack of oxygen, as well as the location, part of the brain may "die", rendering that portion of the brain inoperable. This is also known as a stroke.
