Question

Why is cellophane membrane semi-permeable, even though urea, uric acid and creatinine can diffuse in dialysis?​

Answer 1

Answer:

Question :

Why is a semipermeable membrane used in dialysis?

Answer :

The blood and dialysis fluid are separated only by a thin wall, called a semipermeable membrane. This membrane allows particles that the body needs to get rid of to pass through it, but doesn't let important parts of the blood (e.g. blood cells) pass through.

Question :

What type of membrane is used in dialysis and why?

Answer :

The semipermeable dialysis membrane is designed to prevent the loss of large quantities of plasma proteins into the dialysate. Therefore, drugs that are heavily protein bound are not removed by dialysis.
