Liver Transplantation
Donors
Nearly all donated livers come from people who are Brain Death and whose heart is still beating. The blood type and heart size of the donor and recipient must match. Some transplants come from living donors, who provide part of their liver, which is possible because even part of a healthy liver is enough. A few transplants come from people who are brain dead and whose heart has stopped beating. However, the liver from such donors is often damaged because it was not receiving blood.
