An artificial process by which the toxic waste products of food and excess water are removed from the body Dialysis therefore takes over some of the work normally performed by healthy kidneys The name dialysis comes from a Greek word meaning 'to separate' - i e , to separate out the 'bad things' in the blood from the 'good things'
A process that allows diffusion of solutes dissolved in blood across a semi-permeable membrane into another solution and vice versa This means it removes waste products through this special membrane and bicarbonate can diffuse across to the blood to neutralize acid In this way an imbalance in the body caused by kidney failure can be corrected
the process of separating crystalloids and colloids in solution by the difference in their rates of diffusion through a semipermeable membrane, used to remove metabolites and toxins from body fluids
a way to partially replace the work of the kidneys; with dialysis, the blood is cleaned either by using a special solution and the tissues within the body (peritoneal dialysis) or with an artificial kidney machine (hemodialysis)
Dialysis is a form of diffusion, i e , a form of filtration to separate a crystalloid from colloid substance in a solution by interposing a semi-permeable membrane between the solution and water The crystalloid substances pass through the membrane into the water on the other side, the colloids do not
a procedure for cleansing the blood using membranes to filter out waste elements Kidney dialysis is used to substitute for the function of damaged or absent kidneys
n (die-AL-eh-sis) Mechanical process that partly performs the work that healthy kidneys normally do The main functions of dialysis include clearing wastes from the blood; restoring proper balance of certain electrolytes in the blood; and eliminating extra fluid from the body For people with end-stage renal disease, dialysis is the only way to prolong life, other than receiving a kidney transplant
- the process of artificially cleansing the blood in persons whose kidneys no longer function properly Dialysis can be done either by hemodialysis or peritoneal dialysis
A separation operation in which substances in solution having widely different moleuclar weights are separated by diffusion through a semipermeable membrane
Separation of substances in solution by means of their unequal diffusion through membrane, such as separation of colloids from solubles See also (1) renal dialysis (2) hemodialysis (3) IPD (4) CAPD (5) CCPD (6) peritoneal dialysis
