Biology B3 3.4 Kidney transplants.

HideShow resource information
What can a diseased kidney be replaced by?
A healthy donor kidney.
1 of 10
What must the donor kidney be?
A very good 'tissue match' to the recipient to prevent rejection.
2 of 10
What needs to be done to the immune system of the recipient of a donor kidney and why?
The immune system has to be 'suppressed' or it is likely to reject the new kidney.
3 of 10
What are the advantages of kidney transplants?
For most patients a kidney transplant is a better option than dialysis, the diseased kidney is replaced with a healthy one.
4 of 10
Where are kidneys obtained?
From a victim of a fatal accident or sometimes from living donors.
5 of 10
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'.
6 of 10
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.
7 of 10
What are the risks of a kidney transplant operation?
Aside from the usual risks associated with operations, treatment before and following transplants involve suppressing the patient's immune system which leaves the patient vulnerable to common infections.
8 of 10
What happens the the failed kidneys?
They are usually left in place.
