Organ donation is when a person allows healthy transplantable organs and tissues to be removed, either after death or while the donor is alive, and transplanted into another person.[1][2] Common transplantations include: kidneys, heart, liver, pancreas, intestines, lungs,bones, bone marrow, skin, and corneas.[1] Some organs and tissues can be donated by living donors, such as a kidney or part of a lung,[2]but most donations occur after the donor has died.[1]
