A cadaveric donor refers to an individual who has donated their organs or tissues after death. This process typically occurs when a person has been declared brain dead or has suffered cardiac death, allowing for the recovery of viable organs for transplantation. The organs can include the heart, kidneys, liver, lungs, and pancreas, among others. The use of cadaveric donors is crucial in addressing the shortage of available organs for patients in need of transplants. Organizations like the United Network for Organ Sharing (UNOS) manage the allocation of these organs, ensuring they are distributed fairly and efficiently to those on waiting lists.
