When a person dies, it is not that all the parts of the body stop working together. There are some organs that survive for a few hours even after death and if taken out on time, you can save someone else’s life through organ donation (organ donation). According to doctors, the lifetime of different organs varies after the body is dead and there is a certain “time window” to preserve them.
The question is, which part of the body survives after death? There has been a lot of research in the field of science about this. People usually understand the meaning of death that the heart has stopped beating while this is a long process. This process is called decomposition. Even after the person’s death, he can be kept alive. Keeping organs alive means to do Organ Donation. Now it is important to understand which organ can survive for how long after the death of a person and who can donate the organ. But first we know what changes occur in the body after death.
What changes in the body starts immediately after death
What changes happen in the first hour
Forensic Medicine Department at Deendayal Upadhyay Hospital, Delhi I say Dr. BN Mishra says that the skin color begins to fade within an hour of death. The body temperature starts falling. The flexibility of the muscles starts to end. The liver stops working but despite the lack of oxygen, he is trying to survive somehow. To transplant it, it is necessary to remove and preserve immediately from the body.
Heart stops working
Every minute after death, some changes begin to happen in the body. The first reaction makes us heart and stops working. After the heart, our langs stop working because the body stops demanding oxygen as soon as the heart stops working.
Lungs stop working
The brain also stops working as soon as the lungs stop, because the brain needs oxygen to work, which it does not get after the heart work. After this, due to the closure of heart pumping in our body, blood starts shifting towards the lower part of the body. This process is called Liver Mortis.
The time limit of survival of the fire:
It is important to note that these are only estimated time limitations and the real time can vary according to the limb and the person. Keep in mind that these organs have to be kept in the process of 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
Eyes 4-6 hours
Why death in hospital is necessary for organ donation
For organ donating organs, regular supply of oxygen is necessary even after removing it from the body, this facility can be available in the hospital itself. After brain dead, there is a lack of oxygen in the body. The functioning of all organs without oxygen starts deteriorating. Therefore, they have to take the necessary oxygen supply as soon as possible after death. Within a short time, one organ also has to be transplanted to another body.
