Could you please the difference between hemodialysis and ultrafiltration in layman's terms?

Post date: February 28, 2013
Hemodialysis is one of the machines that we use to replace some of the functions of the kidney.  The kidney performs many functions and a hemodialysis machine can replace some of those functions.  Ultrafiltration is the removal of fluid volume from a patient.  Ultrafiltration (fluid removal) is one of the functions of the kidney and the hemodialysis machine.  The other function that a hemodialyis machine is capable of is to perform dialysis (cleaning) of the blood in order to remove the toxins and built up wastes from the body.  Hence the combination of dialysis and ultrafiltration constitute hemodialysis.
