Question

Explain, why a haemodialysing unit called artificial kidney?

Short Note

Solution

The haemodialysing unit filters nitrogenous wastes from the blood. The dialyzing unit is composed of a cellophane membrane surrounded by a dialyzing fluid. Blood from a convenient artery is channelized to the dialyzing unit. Nitrogenous wastes are filtered through the cellophane membrane because of osmosis. After that filtered blood is channelized back into the body. Since a dialyzing unit substitutes the function of kidney hence it is called an artificial kidney.
