Because oxygen is used to burn glucose, the fuel preferred by the brain. At rest, you use about 20% of the oxygen you breathe to keep your brain running.
16% You'll pass out at anything less.
Human body needs about 78 percent oxygen.
75
ALL of the the organs in the human body need an oxygen supply. This even includes the organs responsible for delivering oxygen to the rest of the body: the heart and lungs. Every organ requires oxygen. All that can be said in this case is that some organs use/need more oxygen than others. For instance, the brain needs/uses more oxygen than the spleen.
Your cells need the oxygen to function. That's why it's called "cellular respiration."and you blood needs to be oxygenated so it can carry the O2 (oxygen) to other parts of the body.
If you are talking about how many percent the human body is made out of, 65%
It helps heart and lungs to function properly.Cells utilize oxygen to produce ATP.It is also used as fuel to burn the glucose to produce energy.Then it absorbs the energy from the glucose coming from the food
the process of exchanging gases
oxygen
In Rest a normal human (65 Kgs Body Weight) will need 250ml/min. of oxygen.Depending on the activity the body might consume 15 times as much oxygen as it needs in rest.
a human breaths 20 liters / minute with oxygen being 21% of the air this means +- 4liters / min intake although a lot of the oxygen leaves our body again when exhaling (4% oxygen gets taken in by our body, and 4% extra CO2 is exhaled) this means a human body takes about 0.16liters of oxygen / minute
oxygen if everywhere. In the heart, lungs, blood. YOu need blood everywhere to live!
What must the human body need to get energy from food is to use oxygen to produce ATP which will fuel the cells.
Oxygen is important because our cells need oxygen to survive. If they don't get oxygen then the cells will die the the human itself will die.

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.
please help i need to know the answer?

Squirrels need oxygen, just as humans do, so they breathe in air much the same way as humans do. Squirrel blood cells need oxygen to operate their muscels, bones, and anything else in their body, much the same need for oxygen in humans.
because they are just like human beings. we need oxygen.
