Solution

Haemodialysis
(1) Haemodialysis is a technique used to clean blood.
(2) When the kidneys are affected due to injury, infections or restricted blood flow, they are unable to filter out nitrogenous wastes from the blood. This results in the accumulation of wastes, a condition called kidney failure.
(3) A dialyser or dialysing machine is used to remove nitrogenous wastes from the blood.
(4) At one time, about 500 ml blood is passed through the dialyser. The purified blood is pumped back into the patient’s body.
