Explain, why a haemodialysis unit called an artificial kidney?
The main function of filtration of nitrogenous wastes from the blood is performed by the haem dialysing unit, which is made of a cellophane membrane. This membrane is surrounded by a dialysing fluid. The dialysing unit receives the blood from an artery post which is filtered, and the nitrogenous wastes are filtered. After this process, the filtered blood is sent back to the body. The filtration of wastes happens through the process of osmosis, and in this way, the functions of a kidney are performed by the dialysing unit, which is often labelled as an artificial kidney.
