Question

Write the difference between clinical death and biological death.

Answer 1

Hint: Clinical death is the kind of death that happens because of the failure or death of an important organ such as the brain or heart or lungs. Yet, different organs of the body function only for a limited period. Biological death is the kind of legal death of the body, in which the whole system ceases to function but specific organs remain to act for a period.

Complete answer:
The phenomenon in which complete and irreversible blockage of circulation, respiration, and brain function occurs is known as clinical death while the phenomenon that happens at the molecular and cellular level because of the degeneration of cells or tissue is known as biological death.
Clinical death may be reversible i.e. an individual can be revived if it's not too late while biological death is irreversible i.e. an individual cannot be revived if biological death has taken place. In clinical death, cells and organs stay alive for limited hours after death. Therefore, transplantation or donation of the organ is allowable and accepted only within a stipulated period while in biological death, the organs of a person become dead almost immediately after the demise of a person, and thus organs cannot be utilized for transplantation. Clinical death is always declared in a death report and justification is given as the failure of kidney, stoppage of brain functioning, failure of heart, asphyxia, and such while in biological death, doctors declare a person dead only after a physical examination such as no breathing, no heartbeat, movement of eyelid halts when light is focused on it and body losing its normal warmth.

Note:
Clinical death is not permanent i.e. reversible, while biological death is permanent i.e. irreversible. A person's brain can remain alive for up to roughly 4-6 minutes after a heartbeat and the breathing halts. If it is greater than 4-6 minutes elapse, nonetheless, the person will most likely experience permanent death and irreversible brain damage or biological death.
