                      1. Normally carried out 3 x a week for 4 hrs
                        1. Done in hospital with medical supervision

                                2. 3) Filtered blood is returned to the patient
                              2. Kidney Transplant
                                1. The diseased kidney can also be replaced by a healthy donor kidney
                                  1. The Kidney could be rejected by the immune system
                                    1. Antigens on the surface of cells tell your WBC's your cells are self cells
                                      1. antibodies are released to attack & destroy foreign & unrecognised cells
                                      2. Blood & tissue type checks must be carried out before a donation
                                      3. Problems
                                        1. Transplant patients have to take immunosuppressant drugs for the rest of their lives
                                          1. A transplant last only 8 yrs on average
