It is said that the human body stops functioning completely only after death, otherwise the organs of the body keep working all the time while sleeping, waking up, eating and drinking. But do you know that this is not completely true.

Actually, after a person dies, all the parts of his body do not stop working together. There are some organs which remain alive for many hours even after death and continue doing their work. Therefore, even after death, other people’s lives can be saved by donating human organs. In such a situation, let us know which parts of the body remain alive even after death and which part dies last.

Which organs remain alive even after death?

According to doctors, the lifespan of all body parts is different. In such a situation, some organs can also be preserved. Even after death, the heart remains alive in the human body for 4 to 6 hours, lungs for 4 to 8 hours, liver for 8 to 12 hours, kidney for 24 to 36 hours, skin for 24 hours and eyes for 4 to 6 hours. Let us tell you that this is not exact timing but approximate time. In such a situation, the survival time of organs depends on many other factors.

How do organs remain useful even after death?

All organs are very important in the human body, be it eyes or heart. In such a situation, these essential organs remain as important even after a person’s death as they were when he was alive. Due to this, many people donate their organs after death because some vital organs of the body remain alive for several hours after death, which can be useful to a living person. This process is called organ transplantation. In this, organs are removed from the body of a dead person, preserved in suitable conditions and transplanted.

Which organ remains alive the longest?

After death, the kidneys remain alive for the longest time in the human body. It remains alive for approximately 24 to 36 hours. Therefore it is considered the most durable organ. In such a situation, after death you can easily donate kidney to anyone and this is the reason why kidney transplant operations are often successful.

Till now, if the deceased person has had diabetes or high blood pressure in the case of organ donation, then his limbs were rarely accepted for transplant. But recently, the Indian Society for Organ Transplantation (ISOT) has released a detailed report for the first time that such organs can be used, provided they are in the right condition and live up to medical standards.

What was said in the report

ISOT report, which has been published in Lancet Regional – South -East Asia, states that India does not have such sufficient data. But according to international data, 15-20 percent of the deceased organists have high blood pressure and 2-8 percent diabetes. Evidence from USRRDs and UNOS databases of the US suggests that in these cases the risk of primary non-function, acute rejections or delayed graft function (DGF) may increase slightly after kidney transplant. However, overall, the effect on graft survival is minor.

In a conversation with Times of India, Dr. Dinesh Khullar, senior nephrologist and co-writer of the ISOT report, said, “On the basis that the deceased was diabetes, it is wrong to dismiss the organ immediately. Our team has suggested a screening criterion, so that the diabetes is safe for using the diabetic donor or not. Evaluate the position of the resipient separately and then decide. “

Impact of diabetes and high BP

Uncontrolled diabetes damages the kidney blood vessels over time, which can reduce the ability to filter the kidney. At the same time, high blood pressure also weakens it by increasing the pressure on the kidney. Despite this, organ is not unusable in all cases. Many times the organs are also completely healthy.

Dr. Shiv Sarin, director of the Institute of Liver and Beller Sciences, also told Times of India, “Diabetes, high blood pressure or even the organs of the deceased donors who have history of cancer can also be used for transplant, but every case is necessary. Should, because in one-third of cases, the liver can be used to take care of the kidney from high BP donor.

Why this change is necessary

Experts believe that this new thinking may increase the number of organ donation. With this, thousands of patients sitting in waiting for transplant will get new life. However, it is necessary that strict medical testing and personal case-case should be evaluated before the transplant.

Human body is not less than a machine. Even if a person is declared medically dead, even all the parts of his body do not stop working immediately. It has become possible from the process of modern medical science and organ donation that even after death, some organs are given new life to the needy. This process is mainly possible in the case of people declared brain dead, as blood circulation and oxygen supply in their body is maintained by artificial means, so that the organs can be kept alive for some time.

Which organs live after death?

The life period of different organs is different, which is directly related to the time limit of their transplant. After removing the organs from the body, they are kept in special solution and at cold temperatures so that their functionality is maintained.

Here is the estimated time frame of some major limbs and their transplant.

• Heart: The heart is one of the most sensitive organs. It is considered best to transplant within 4 to 6 hours after death.
• lungs: The lungs also need to transplant within 4 to 6 hours similar to the heart. They are also highly sensitive to time.
• Liver: The liver can be kept safe for 8 to 12 hours for transplant. Its comparatively long period makes it more favorable for long distances transport.
• Pancreas: The pancreatic can usually be used for transplant from 12 to 18 hours. According to some sources, it can also be up to 24 hours.
• Intestons: It is necessary to transplant the intestines within 8 to 16 hours.
• kidney: Kidney is one of the longest surviving important organs. It can be protected for transplant from 24 to 36 hours after death, in some cases even for 72 hours. This is why the number of kidney transplant is higher than other organs.
• Eyes: The cornea of the eye can be extracted within 6 to 8 hours after death. However, the cornea tissue can be stored for 14 days after removing, which gives more time for transplant.
• skin: Skin tissue can be extracted within 24 hours after death and it can be stored up to 5 years after a special process.
• Bones: The bones can also be stored for 5 years within 24 hours.
• Heart Valve: Heart valves can be removed after death and can be stored for 10 years.

Organ donation process and challenges

Donation of vital organs is possible only when the person has been declared ‘brain dead’ in the hospital and kept on ventilator support. This is so that the organs get oxygen and they are viable. If a person dies due to stopping at home or heart rate, then the donation of his vital organs is usually not possible, because the organs are damaged in a few minutes due to lack of oxygen. Time is very important in transplantation of organs, which is called cold ischemia time. During this time, the organ is taken out of the body and kept in a cold environment. The less time it takes in this process. The success rate of transplant is equally better.

Ang donation is a life -saving work. It is important to understand that even after death some of our organs live for some time and they can give precious gifts of life to someone else. Due to the progress and quick response systems of medical science, it has now been possible that these organs can be transplanted successfully, giving thousands of people new expectations.
