    "An alternative method of dialysis is peritoneal dialysis. In this instead of the blood being cleaned using an artificial membrane outside the Body it is cleaned inside the body. It used the peritoneum , the thin membrane that surround the organs of the abdomen. The peritoneum is well supplied with blood vessels. This membrane has two layers and the space between them is used as a reservoir for the dialysis fluid. The fluid remains in the body for a few hours after which it is drained out and replaced without fresh dialysis fluid. This procedure needs to take place four times a day"

    1) explain why the peritoneum is a suitable membrane for dialysis within the body
    2) using the information provided and your own knowledge suggest why peritoneal dialysis needs to take place four times a day whereas haemodialysis only needs to take place three times a week
    3) suggest how the dialysis fluid may be altered to allow more water to be removed from the blood
    4) if peritoneal dialysis is used for long term treatment the peritoneum becomes thickened. Suggest how and why this affects the efficiency of peritoneal dialysis
