A beating heart cadaver is kept alive in order to keep its organs from decaying before they can be transplanted. Surgeons will remove the organs, one after the other, and give them to their patients. The entire recovery process is usually completed within four hours. This process was formerly known as an "Organ Harvest", but the name has since changed to the milder "Organ Recovery." Many organs can be used, and many lives can be saved by one body. The bodies are generally organ donors, who have agreed beforehand to donate their organs. Some donated organs are taken from non-heart-beating donors. Organs from brain deaths, however, have a better success rate, and currently most organ donation is from these deaths.
