FUNCTION OF KIDNEY

To filter the blood contains both useful

substances (glucose) and waste products

(urea).

It will form urine and flow through ureter into

the urinary bladder

THE PROCESS OF DIALYSIS

(PMR 06 &07)

During hemodialysis, the patients blood ispumped into the dialysis machine which containsa series of semipermeable tubing (salur separatelap). At the same time, dialysate is pumpedthrough the machine.

Blood cells and dialysate do not mix togetherbecause they are separated by thesemipermeable tubing.

Urea, excess water and salts from the patientsblood are diffuse through the semipermeablemembrane into the dialysate.

The wastes are then removed from the

dialysis machine.

The blood that flows into the patients body isnow clean and free from waste product.
