Question

Quizplus · Accepted Answer

During peritoneal dialysis, the peritoneum acts as a semipermeable membrane through which wastes move from the blood by diffusion and osmosis. It allows for the removal of excess metabolites and other waste products from the body. Option A is incorrect because excess metabolites are the reason why the peritoneum is more permeable, not the cause. Option B is incorrect because ultrafiltration is the movement of fluid across a semipermeable membrane under pressure, whereas in peritoneal dialysis, the movement of wastes occurs mainly through diffusion and osmosis. Option D is incorrect because solutes in the dialysate do not enter the bloodstream through the peritoneum, rather they help remove waste products by creating a concentration gradient.
