Dialysis is a procedure by which waste products which would normally be removed by the kidneys are removed by diffusions across a semipermeable membrane. This procedure is done when the kidneys have failed, or when a dangerous toxin is present in the blood and needs to be removed quickly.
There are two kinds of dialysis for renal failure: hemodialysis, where the blood is filtered through a machine; and peritoneal dialysis, where the abdominal peritoneal lining is used as the semipermeable membrane across which the toxins are filtered.
Each of these methods has benefits and drawbacks. You should talk to your physician if you or a loved one need or are contemplating dialysis.
Here's how it works. The dialysis machine removes the blood from the body (all of it, over time), filters out the contaminants, and moves it back into the body. This takes a horrible toll on a person, and usually requires a lengthy recovery afterwards.
In medicine, dialysis (from Greek dialusis,"διάλυσις", meaning dissolution, dia, meaning through, and lysis, meaning loosening or splitting) is a process for removing waste and excess water from the blood, and is used primarily to provide an artificial replacement for lost kidney function in people with renal failure.[1] Dialysis may be used for those with an acute disturbance in kidney function (acute kidney injury, previously acute renal failure), or progressive but chronically worsening kidney function-a state known as chronic kidney disease stage 5 (previously chronic renal failure or end-stage renal disease). The latter form may develop over months or years, but in contrast to acute kidney injury is not usually reversible, and dialysis is regarded as a "holding measure" until a renal transplant can be performed, or sometimes as the only supportive measure in those for whom a transplant would be inappropriate.[2]
The kidneys have important roles in maintaining health. When healthy, the kidneys maintain the body's internal equilibrium of water and minerals (sodium, potassium, chloride, calcium, phosphorus, magnesium, sulfate). The acidic metabolism end-products that the body cannot get rid of via respiration are also excreted through the kidneys. The kidneys also function as a part of the endocrine system, producing erythropoietin and calcitriol. Erythropoietin is involved in the production of red blood cells and calcitriol plays a role in bone formation.[3] Dialysis is an imperfect treatment to replace kidney function because it does not correct the endocrine functions of the kidney. Dialysis treatments replace some of these functions through diffusion (waste removal) and ultrafiltration (fluid removal).[4]
Process of removing blood from a patient with kidney failure, purifying it with a hemodialyzer (artificial kidney), and returning it to the bloodstream. Many substances (including urea and inorganic salts) in the blood pass through a porous membrane in the machine into a sterile solution; particles such as blood cells and proteins are too large to pass. This process controls the acid-base balance of the blood and its content of water and dissolved materials.
Basically, they hook you up to a machine for hours, and filter ALL your blood because a person's kidneys aren't able to.
Kidney dialysis helps the waste inside your blood(body) to come out
to prevent the kidney failure person by death or getting disease and to process excretion system/to release the mineral salts by urine
Two thin needles will be inserted into your AV fistula or graft and taped into place. One needle will slowly remove blood and transfer it to a machine called a dialyser or dialysis machine.
The official definition for the word dialysis is "the clinical purification of blood by dialysis, as a substitute for the normal function of the kidney."

Continuous ambulatory peritoneal dialysis (CAPD) - the process of dialysis is done while the patient goes about his/her normal daily activities.Outpatient dialysis.
during dialysis the blood is is flowin through a closed system
hunulity process occur in dialysis because it helps pump the blood stream
Patients with kidney disorders need to be treated with dialysis. Devices that perform dialysis are simply called dialysis machines (dialyzers). For more information on dialysis follow the links below.
Dialysis
It is a machine called the dialysis.
If you are on dialysis, no you can not stop kidney dialysis. Dialysis is what cleans all the toxins from your blood. If you were to stop dialysis you will build up all the toxins. And will start feeling really awful. You might end up getting a heart attack, stroke, or just die.
