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.
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.
Oxygen is needed for aerobic respiration in the mitochondria in our cells. Therefore, it would be reasonable to assume that the cells which respire most need the most oxygen ie. our muscles. The muscles need far more oxygen relative to other systems in our body, due to the fact that they respire most. This is especially true during rigorous exercise.
Humans need to breathe in order to take in oxygen from the air, which is essential for the body to produce energy through a process called respiration. Oxygen is used to fuel the cells in our body and remove waste products like carbon dioxide. Without oxygen, our cells would not be able to function properly, leading to organ failure and eventually death.
The human body can survive without the spleen, gallbladder, and one kidney.
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
oxygen
oxygen if everywhere. In the heart, lungs, blood. YOu need blood everywhere to live!
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.
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.

Oxygen is used to help people breathe in and out
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.
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
depends on your body. but less than you prob need. watch survivorman on discovery channel.
a lot of liters.
The function of the circulation unit in the human body is to transport oxygen, nutrients, and waste products throughout the body via the blood vessels, ensuring that all cells receive what they need and waste is removed efficiently.
because you need oxygen throughout your body
