What organ in the human body uses 40 percent of the oxygen in your blood?
The brain consumes 40% of the oxygen in your blood.
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.
What do red blood cells do in the brain?
Red blood cells don't get as far as the brain itself; they do enter the head, and provide oxygen to the cerebro-spinal fluid in which the brain bathes. What you should understand about red blood cells and the brain is that the brain is an unusually delicate organ, in which a red blood cell can actually get in the way of the normal function of the brain, by intruding into a nerve synapse. That is why the brain does not use blood directly, as other organs do.
How many blood cells are in the brain?
While the brain does not contain blood cells in the same way as blood vessels or circulating blood, it does have microglial cells that act as the immune cells of the central nervous system. These cells can help defend the brain against infections and remove cellular debris.
When the blood supply to a portion of the brain is blocked this is caused?
When the blood supply to a portion of the brain is blocked this causes a stroke.

What parts of the brain doesn't have blood brain barrier?
Area postrema doesn't have blood brain barrier
How much blood is used by the brain?
Well, 20% of the oxygen we take in our blood is used by the brain. Thus, relatively the same amount of blood would be used by the brain.
Why is brain white yet has blood in it?
because the blood is inside the the brain not around it
The blood-brain barrier shields brain cells from toxins by?
The blood brain barrier (BBB) is composed of a high concentration of endothelial cells in the brain's capillaries, which help to prevent toxins from passing into the brain from the blood supply.
What is a swollen blood vessel in your brain?
A swollen blood vessel in the brain is called a brain aneurysm. It is a potentially life-threatening condition where a weakened area in a blood vessel in the brain balloons and fills with blood. If an aneurysm ruptures, it can cause a hemorrhagic stroke.
Does the brain need blood to survive?
yes the brain can think with the blood flowing smoothly
Alcohol gets to the brain through?
