If the kidney failure cannot be otherwise treated by drug and dialysis, the patients are advised for kidney transplantation. Grafting a kidney from a compatible donor to restore kidney function in a recipient suffering from kidney failure is called kidney transplantation. Donated kidney may come from a living person or a donor who has recently died. The genetic makeup of the donor should be as close to the patient as possible, that is, if it is donated by a close relation, it reduces the chances of rejection. Drugs are, however, used to prevent rejection of the transplanted kidney by the body.
It excretes bile pigments, cholesterol, drugs and some vitamins.
Production of bile juices that help in the breakdown of lipid molecules.
It excretes all the above mentioned in bile, which flows into the small intestine and from there these get removed with the faeces.
Formation of urea and uric acid (from ammonia) also takes place in liver. These are removed from the body by the kidneys.
