Kidney Dialysis
Kidney Dialysis, also known as hemodialysis, medical treatment used to remove waste materials from the blood of patients lacking renal function (see Kidney ). Blood from an artery is pumped through a dialyzer, or artificial kidney, where it flows past a semipermeable membrane . Dialysis fluid passing on the other side of the membrane removes unwanted elements in the blood by diffusion . The blood is then returned to the body through a vein .
