3 to 5 minutes to brain death is normal, anything over 5 minutes will result in permanent brain damage, but people have been drowned in very cold water and recovered after hours of no oxygen, the rapid loss of body temperature saved the brain tissue by slowing brain cell deterioration.Up to 16 minutes
The human brain has four lobes of the cerebral cortex. Each lobe in the human brain is named from the bone that covers the lobe.
The brain is found in the skull within the head of the human.
cerebrum, cerebellum, and the brain stem
Neurons make up the complete complex network of the human brain. The brain contains about 100 billion nerve cells to work the body..
The mechanism for pulmonary ventilation is the respiratory system in the human body. Oxygen-rich air is breathed in and carbon dioxide is breathed out.
Trees help to reduce global warming by 'cleaning the air'. Here's how: * A gas that helps to cause global warming is carbon dioxide. * Trees 'breathe' just like we do except when they breathe they take in carbon dioxide not oxygen. * When a tree breathes out it breathes out oxygen. * This is then breathed in by a human. * Carbon dioxide is breathed out the the human... * ...and breathed in by the tree... * This carries on continuously.

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.
Yes. In fact, such is the brain's demand for oxygen that it requires 20% of your total oxygen supply. This explains why it is served by so many blood vessels.
Asphyxiation - lack of Oxygen to the brain!
The human brain is just like any other organ in the body, it needs oxygen and nutrients in order to survive. The blood is the main supplier of the body (including the brain) oxygen.
The brain consumes 40% of the oxygen in your blood.
The human brain consumes 25% of the body's oxygen compared to 15% for the kidneys and 7% for the heart.
