Various Stages Of Death

Whatever happen or may not happen,, but deathly is the ultimate truth. If you are corporeal then one day you will  be a corpse, die and vanish into this earth.
So lets have a knowledge on various stages of death,
Isn't it exciting

The death undergoes three steps before one is finally dead

Clinical death:

It  is the point at which a person's heart stops beating. At that time, breathing and blood circulation stop.

 Brain death :

When the heart stops, oxygen cannot be transported to the brain The brain simply cannot survive for very long without oxygen.When oxygen is withheld beyond  a four to  six-minute threshold, brain death is the result.When brain death occurs, all neurological functions irreversibly cease.The legal time of death is noted at the moment in which a doctor determines that a patient's entire brain has ceased to function.
but It's still possible to resuscitate a person who has undergone clinical death and keep them alive by artificial means of life support, such as a respirator.

 Biological death

when brain has been too long deprived of oxygen, resuscitation is impossible. Then the  biological death will be  established
It is  called somatic death in scientific term
Somatic death is the death-- the permanent, irreversible death-- of an organism as a whole. In humans it is usually after brain death, as the other vital organs are unable to function without the brain. With modern technology, though, one can be brain dead but still have circulation and respiration artificially. In such a case one isn't somatically dead because other organs are still alive. Once artificial support is removed somatic death occurs, because the person is then entirely and completely inactive with regard to brain, circulation, and respiration.
