The organs most frequently donated are kidneys, corneas, heart, lungs, liver, and pancreas. Certain organs can be donated during a person’s lifetime; some are only used following brain death. All donors should be free of cancer, serious infection (such as hepatitis B), and should not carry HIV. Organs for transplantation must be removed within a few hours of brain death, and before or immediately after the heartbeat has stopped. In some kidney transplants, the kidney is provided by a living donor, usually a relative whose body tissues match well on the basis of tissue-typing. Suitable related donors may also provide bone marrow for transplantation and sometimes skin for grafting.
