What defines a 'living donor'?

A living donor is defined as someone who donates an organ or part of an organ while still alive. This definition is significant in the field of organ transplantation, as such donations can be lifesaving for recipients in need of transplants. Living donors often donate kidneys or part of their liver, since these organs have the ability to regenerate.

This form of donation is carefully regulated and requires extensive medical and psychological evaluations to ensure the donor's well-being and the safety of the procedure. The option highlights the primary aspect of living organ donation, which is the act of providing an organ while the donor is still alive, ensuring that there is an ongoing commitment to donor health and safety.
