1. At the clinic, the dialysis machine is set up with a dialyzer containing a semipermeable membrane that only allows small solutes to pass through. The patient's blood flows from his body through the dialyzer on one side of the membrane and is then returned to his body. At the same time, the machine flows dialysate, the fluid used to clean the blood, through the dialyzer on the other side of the membrane in the opposite direction. The dialysate contains isotonic electrolytes like NNNN+, KK+,aaaaaa CCCC22+, and molecules like glucose. a. Which of the components of blood listed below cannot cross the dialysis membrane? Glucose Blood cells Urea Proteins Na+ ions Water K+ ions Ca2+ ions b. Why are glucose and electrolytes, which are not waste products, included in the dialysate? C. Based on your answers to (a) and (b), for each substance that can move across the membrane, state whether it will move into the blood, out of the blood, or in both directions. Explain your reasoning.
