In recent years doctors have been able to take parts from one human body and put them into another
human body. This has been called "transplanting (移植)". The parts of the body which are transplanted usually
come from the body of a person who has recently died. The most successful transplant has probably been the
transplant of the human eye. The most exciting transplant has been the transplant of a human heart from one
person to another. The human body often does not accept the new part completely. It often accepts it for a
short time but then refuses it. This means that the rest of the body will not work with the new part. The
person who has received the new part then dies.
