Dialysis

Dialysis is the process of removing the water and other wastes from the body through filtration of the liquid by a semi-penetrable layer. Diffusion is a general property in water substances in which water can move from a territory of high fixation to a range of low fixation. There are two primary types of dialysis; they are Hemodialysis and peritoneal dialysis which will eliminates wastes and water present in the blood in number of ways. Hemodialysis removes the waste water present in the body by rotating the blood outside the body through an channel of external filter which is called a dialyzer that is consisting of a semipermeable layer.

There is two types of dialysis they are:

a. Hemodialysis: This is very essential with the patients suffering from renal failure. In this procedure of treatment, an artificial kidney is applied which purifies the blood. There will be made an "access" usually in the forearm of the hand from where blood can easily be taken out from the body and directed to the artificial kidney for complete purification such that to remove the wastes from it.The access initially collects the blood from patient body and experiences purification in artificial kidney and again injected the purified blood in to patient body.

b. Peritoneal dialysis: This is a process to remove the waste products present in the body when the kidneys cannot sustain their job. There will be no artificial kidney is used in this process. The peritoneum which is the lining inside the abdomen is used for filtering instead of artificial kidney. This Peritoneal dialysis is of two types they are mainly continuous cycling peritoneal dialysis and constant ambulatory peritoneal dialysis. The Peritoneal dialysis is used in kidney failure patients for the treatment of the kidneys to eliminate the wastes from the body.
