Answer 2

When there is no blood actively being pumped to the brain, the nerve cells in the cerebral cortex die in two minutes. The nerve cells in the midbrain that control unconscious activity such as breathing can last thirty minutes and the nerve cells in the spinal cord can last an hour without blood flow. The brain has no way of storing oxygen. Nerve cells require oxygen and glucose to function. If the heart were not pumping, the oxygen in the stagnant blood would be used up by the cerebral cortex in two minutes.

Answer 3

First understand that it won't make much difference to the person shot - most brain damage caused by a gunshot to the head removes any personality/memory and results in brain death. A heart can just go on beating for years after the brain is comatose. If the bullet hits the back of the brain where it meets the spinal cord - that can stop the heart. Mostly a head shot is as fatal as a heart shot but people survive more head shots that heart ones. The heart can also be kept alive outside the body - we haven't gotten good enough to do that with a human brain yet.

Answer 4

If the "heart beat stops," then the heart is really not "functioning" exactly.

There may be some electrical activity going on in/around the heart after the heart beat stops, but the length that this electrical activity lasts varies from person to person. When a person has no heart beat but still has electrical activity, that person may commonly be in what is called "ventricular tachycardia" (V Tach) or "ventricular fibrillation" (V Fib).

Also, electrical activity can sometimes be affected by drugs that are given by medical personal when a person has a cardiac arrest (and is in V tach or V Fib), so it is hard to say exactly how long the heart's electrical activity will last after the heart beat stops.
