Question

Kidney failure is often treated by hemodialysis, in which blood diverted out of the body is filtered and then allowed to flow on one side of a semipermeable membrane. fluid called dialysate flows in the opposite direction on the other side of the membrane. in replacing the reabsorption and secretion of solutes in a functional kidney, the makeup of the starting dialysate is critical. what initial solute composition would work well?

Answer 1

I think that the initial solute composition that would work well is the presence of sodium ions and other ions (electrolyte) in the dailysate. This would limit the extent to which they would be removed from the filtrate during the dialysis process. Adjusting the electrolyte in the starting dailysate enhances their removal from the filtrate,
