Though Kidney failure is not common, but sometimes kidney infection, injury to kidneys or restricted blood flow to kidneys result in kidney damage and malfunctioning. In order to clean the blood of metabolic wastes and to maintain normal levels of water and mineral ions in body fluids, a matching kidney from another person can be transplanted. But this process is very complex and the success percentage is very low. Instead an artificial kidney can be used. This artificial kidney is called as Dialysis.
Principle of Dialysis: Blood is made to flow into the dialyzing machine made of long cellulose tubes coiled in a tank having a dialyzing solution. Waste substances diffuse out of the blood into the tank. The purified blood is pumped back into the patient.
