From a victim of a fatal accident or sometimes from living donors.

Why may the recipient's body reject a donor kidney?

there are proteins called antigens on the surface of cells, the recipient's antibodies may attack the antigens on the donor organ because they recognise them as being 'foreign'.

What must the recipient of a donor organ do following the transplant to prevent organ rejection?

They must take drugs to suppress the immune response to prevent rejection, these are called immunosuppressant drugs.
