The dialysis machine takes the blood in your veins. Then it takes it through a series of tubes which undergoes filtration by use of reverse osmosis. The clean blood is returned to the body.

Explanation:The dialyzer, or filter, has two parts, one for your blood and one 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.
