Which organ of the body remains alive for how long after death? According to doctors, the lifespan of different organs varies after the body is dead and there is a certain "time window" to preserve them.
When a person dies, it is not the case that all the organs of the body stop working at once. There are some organs that remain alive for a few hours even after death and if removed on time, they can save someone else's life through organ donation. According to doctors, the lifespan of different organs varies after the body dies and there is a certain "time window" to preserve them.
The question is, which part of the body remains alive for how long after death? A lot of research has been done in the field of science about this. Usually people understand death to mean that the heart has stopped beating, whereas it is a long process. This process is called decomposition. Even after a person dies, his organs can be kept alive. Keeping the organs alive means doing organ donation. Now it is important to understand that which organ can remain alive for how long after the death of a person and who can do organ donation. But first let us know what changes take place in the body (dead body) after death.
What changes take place in the body immediately after death
What changes happen in the first hour
Dr BN Mishra of the Forensic Medicine Department at Delhi's Deen Dayal Upadhyay Hospital says that within an hour of death, the skin colour starts to fade. The body temperature starts to drop. The elasticity of the muscles starts to diminish. The liver stops working but despite the lack of oxygen, it somehow tries to survive. For transplantation, it is necessary to remove it from the body immediately and preserve it.
the heart stops working
After death, some change starts taking place in the body every minute. The first reaction is our heart and it stops working. After the heart, our lungs stop working because as soon as the heart stops working, the body stops demanding oxygen.
lungs stop working
As soon as the lungs stop working, the brain also stops working because the brain needs oxygen to work, which it does not get after the heart stops working. After this, when the heart pumping stops in our body, the blood starts shifting towards the lower part of the body due to gravity. This process is called livor mortis.

It is important to note that these are only approximate time frames and the actual time frame may vary depending on the organ and the individual. Keep in mind that these organs have to be kept in proper oxygen supply.
Brain: 3-7 minutes
Heart: 4-6 hours
Lungs: 4-8 hours
Liver 8-12 hours
Kidney - 24-36 hours
Skin 24 Hours
4-6 hours
Why is it necessary to die in a hospital for organ donation
For the organs to be donated, regular supply of oxygen is necessary even after removal from the body, this facility can be available only in the hospital. After brain death, there is a lack of oxygen in the body. Without oxygen, the functioning of all the organs starts deteriorating. Therefore, after death, they have to be taken out of the body as soon as possible and given the necessary oxygen supply. An organ also has to be transplanted into another body within a short time.
