Organ transplantation is a medical procedure that involves removing a healthy organ from a donor and transplanting it into a recipient whose organ has failed or is not functioning properly. The most common types of organ transplants are kidney, liver, heart, lung, pancreas, and intestine transplants. The procedure requires a donor who has agreed to donate their organ, and a recipient who has been identified as a suitable match for the donor organ. Transplantation can be a life-saving treatment for many people with end-stage organ failure, but it is a complex procedure that requires careful screening, surgical skill, and ongoing medical management.
