A transplant is an organ, tissue or a group of cells removed from one person (the donor) and surgically transplanted into another person (the recipient or host) or moved from one site to another site in the same person.
Transplants – such as a liver transplant – can save lives. They can also restore function to improve quality of life. For example, transplanting the clear tissue that covers the eye (cornea) is not necessary for life, but can restore sight.
