Organ transplantation is the process of surgically transferring a donated organ to someone diagnosed with organ failure. Many diseases can lead to organ failure, including heart disease, diabetes, hepatitis, cystic fibrosis, and cirrhosis. Injury and birth defects may also cause organ failure. Organ donors may be living, brain dead, or dead via circulatory death. The different types of transplants are

• Autograft
• Allograft and allotransplantation
• Xenograft and xenotransplantation
• Domino transplants
• ABO-incompatible transplants
• Transplantation in obese individuals
