Question

Explain, why a haemodialysing unit is called an artificial kidney?

Answer 1

Haemodialysis:

• Haemodialysis is a procedure of removing urea from the blood of patients affected by uremia and kidney failure.
• It is called artificial kidney because it replaces the function of the kidney i.e. removing urea from the blood.
• In hemodialysis, the blood passes through a solution that has the same composition as that of plasma but without the nitrogenous wastes i.e. urea.
• Thus, by the concentration gradient of waste, it moves from blood to the dialysis fluid
• The purified blood is then sent back to the body
