How does the dialyzer clean my blood in hemodialysis?

A dialyzer, or filter, has two parts that are used to clean your blood in hemodialysis. One part is for your blood and the other is for a washing fluid called dialysate. A thin membrane separates these two parts. Blood cells, protein and other important things remain in your blood because they are too big to pass through the membrane. Smaller waste products in the blood, such as urea, creatinine, potassium and extra fluid, pass through the membrane and are washed away.
