15 What is ‘Dialysis’?Dialysis is a process for removing waste and excess water from the blood, and used primarily to provide an artificial replacement for lost kidney function in people with renal failure.
16 By dialysis, wastes diffuse out of the blood, across a partially permeable membrane, into a fluid that is constantly renewed.In this way urea is removed from the blood without altering any of its features.
18 When is dialysis required? Acute kidney injuryAcute renal failure
