Dear Student,
The other name for an artificial kidney is haemodialysis.
Healthy kidneys remove excess of fluid, wastes, and minerals from the body. If the kidneys fail to function, wastes may accumulate in the body, the body may retain excess fluid, and blood pressure may rise. This can even lead to death. In such a case, an artificial kidney or haemodialysis is useful. In haemodialysis, only a few drops of blood are allowed to flow, through a special filter that removes wastes and extra fluid. The detoxified blood is then returned to the body. The special filter used in dialysis consists of a number of tubes with semi-permeable lining, suspended in a tank filled with the dialysis fluid. It is used to treat kidney failure. Its main function is to remove the extra fluid and wastes from the blood.
