what means death of a human beeing?how define it?.?

Answer 1

Death is the irreversible cessation of brain function (to be more specific brain stem function). It does not matter what the other organ are doing. The heart, lungs, liver, kidneys etc may be working fine but if the is no electrical activity or blood flow in the brain, the person is dead. This is why we remove organs for transplant from such bodies.

Answer 2

Death used to be defined by heart function, but because of the advent of CPR and ventilators it is no longer an adequate definition. It is now defined as the permanent suspension of consciousness coupled with zero cardiac function.

The definition is still debated because the time of death is important for the use of transplantable organs.

Answer 3

I will add to the transplant surgeon--brain cessation is the current US definition of death and this is measured by EEG--usually 2 several hours apart and brain flow studies--in the dead brain, blood stops flowing and this shows up on a special flow scan; the head is usually cool as well; pupils fixed and dilated suggest brain death, as do other neurological tests ("calorics", "dolls eyes" etc)
