WHAT IF? Kidney failure is often treated by hemodialysis, in which blood diverted out of the body is filteredand then allowed to flow on one side of a semipermeablemembrane. Fluid called dialysate flows in the oppositedirection on the other side of the membrane. In replacingthe reabsorption and secretion of solutes in a functionalkidney, the makeup of the starting dialysate is critical.What initial solute composition would work well?
