DIALYSIS DEFINED
Dialysis is the clinical purification of blood by dialysis, as a substitute for the normal function of the kidney.
It's the process of removing waste products and excess fluid from the body. Dialysis is necessary when the kidneys are not able to adequately filter the blood.
Dialysis allows patients with kidney failure a chance to live productive lives. there are two types of dialysis: Hemodialysis and Peritoneal dialysis.
Each type of dialysis has advantages and disadvantages. Patients can usually choose the type of long term dialysis that best matches their needs.

Dialysis is the medical procedure to remove waste or toxin from the blood and adjust fluid and electrolyte imbalances by utilizing rates at which substance diffuse through a semipermeable membrane:

a: The process of removing blood from artery (as of a kidney patient), purifying it by dialysis, adding vital substances, and returning it to a vein- called also hemodialysis.

b: A procedure performed in the peritoneal cavity in which the peritoneum acts as the semipermeable membrane- called also peritoneal dalysis

During hemodialysis, you will be hooked up to a machine that takes over the kidneys' job of filtering blood.
Before the first session, the doctor will need to create an entrance into one of your vessels so your body can be connected to the filtering machine during each visit. this is called a vascular access. It is a place on your body where blood cam be removed and then returned. this can be done by;

• connecting an artery to a vein to create a larger blood vessel area, called a fistula 
• joining (grafting) an artery and vein together using a soft plastic tube
• inserting a thin plastic tube into a large vein in the neck or groin area of the leg; this type of access is temporary. 

When your kidneys are healthy, they clean your blood. they also make hormones that keep your bones strong and your blood healthy. When your kidneys fail, you need treatment to replace the work your kidneys used to do. Unless you have a kidney transplant, you will need a treatment called dialysis.

Experts recommend creating an access weeks or moths before your first dialysis session so it ha s a chance to heal properly before using it.

How long each hemodialysis session lasts depends on;

• How well your kidneys work
• how much fluid you gain since your last dialysis session
• how much waste has gathered in your blood since lst dialysis session 
• your weight
• the type of hemodialysis machine being used
