tell me diff organs that can be donated after death & their lifespan after death...?

Answer 1

According to medical experts, when the heartbeat of a patient stops, his liver will stop functioning within five minutes and his kidney can keep working only up to half an hour. Therefore, the patient whose heartbeat has stopped basically has no use for a transplant if the transplant surgery cannot be performed immediately. But with a human body whose brain has died, other than the brain and the known diseased parts, all other organs can be used in transplant surgery for other patients. Most countries with an advanced medical science have developed a legal definition of brain death that will ensure the organ transplant is performed under the protection of law. In China, in order to avoid misjudgment of death, the pronounced dead body by the hospital is usually placed in a morgue for 24 hours. If the deceased and his family both agreed to donate organs, most organs would have become useless by then.
On March 29, 2005, Chutian Urban Daily published an article entitled "Two Lives Saved in China's First Transplant Using Organs from Brain Dead Body", which reported the first case in China of a brain dead donor of organs. This was actually done in a legal vacuum, but it also indicated that organ transplants prior to that had never used organs from brain dead donors.
So, the organs China uses for transplant, especially organs that are sensitive to deficiency of warm blood such as heart, liver, and kidney, must mainly come from death-row inmates.
a common practice in CCP-controlled China that death-row prisoners' internal organs were removed before they stopped breathing.
This should make people stop and think before signing anything to donate their bodies when they die!

Answer 2

If it is a beating heart donation, they can take heart, lungs, kidneys, liver, pancreas, intesitines. That means they harvest the organs while the heart is still beating (patient must be clinically brain dead). If the heart stops beating, the kidneys and (sometimes) the liver can be harvested but must be done within approximately 1 hour from cardiac arrest (organs must be out of body within 1 hour from when the heart stops). This is done for people who are brain dead or if brain death is imminent (it will definitly happen). In both cases, an organ donation center is involved in coordinating placement of the organs before they are harvested and teams at the hospital work closely to do testing and preparation for the operation. This whole coordination process can take hours, sometimes almost a whole day, so if someone dies suddenly or unexpectedly, they probably can't donate organs. Sometimes not all organs can be placed for transplant because of their condition or because there is not a suitable recipiant in close enough range for transplant. If that is the case, families may consent for those organs that can't be transplanted to be used in important medical research.
