उत्तर
Principal of dialysis:
The procedure of dialysis is based on diffusion of solutes and ultrafiltration of fluid across a semi-permeable membrane. In dialysis, the blood from a convenient artery is pumped into the dialyser of a dialysing machine. A dialyser contains a coiled cellophane tube surrounded by the dialysing solution. The dialysing solution contains water, glucose and salts, which are similar in concentration to those in normal blood. The porous cellophane membrane of the tube allows the passage of molecules based on concentration gradient. As the patient’s blood is passed through the dialysing solution, most of the wastes (like urea) present in it pass through the selectively permeable cellulose tubes into the dialysing solution, thereby cleaning the blood. The clean blood is pumped back to the body through a vein.
