5.3 VIEW “DIAGRAM FOR QUESTION 5.3” ON THE DIAGRAM PAGE The diаgrаm shоws а simplified dialysis machine. Study it tоgether with the extract given belоw and then answer the questions that follow. Blood from the patient is taken from a vein, pressurised, and transported to the dialysis machine. Once in the machine, the blood flows through small tubes made from a membrane called dialysis tubing. On the other side of the membrane is a liquid called dialysis fluid. The dialysis fluid has a similar composition to blood plasma, but it does not contain any urea. Fresh dialysis fluid flows in through one end of the machine and out the other. It flows in the opposite direction to the blood. The dialysis tubing is partially (selectively) permeable meaning that it only allows certain substances to pass through it. Blood cells and plasma proteins are too large to pass through, but smaller molecules pass through the membrane easily. Urea is at a higher concentration in the blood than in the dialysis fluid, so it diffuses across the dialysis tubing into the dialysis fluid.
