Describe the procedure of dialysis?

　　here are different types on analysis. This info comes from BWH.
　　Hemodialysis: an artificial kidney machine, called a dialyzer, filters the blood, and returns the cleaned blood to your body. You are connected to the dialyzer via tubes that are inserted into a vein in your arm, leg, or occasionally, neck. If hemodialysis is being performed as a temporary measure, then the catheter is likely to be inserted through the neck vein. If hemodialysis is going to be done regularly, then an access site called a fistula or shunt may be surgically created in one of your veins.
　　Hemodialysis is usually done at a dialysis center or hospital, by trained technicians or nurses, or may be done at home with assistance. Hemodialysis is usually done three times a week and each treatment lasts from two to four hours.

　　Peritoneal dialysis: instead of using a machine, this type of dialysis uses the abdominal lining, called the peritoneal membrane, to filter blood. A cleansing solution, called a dialysate, is infused through a tube inserted into your abdomen. Long-term peritoneal dialysis may require the surgical creation of a port in the abdomen through which this dialysate can be infused. Fluid, wastes, and chemicals pass from the tiny blood vessels in the peritoneal membrane into the dialysate, which is then drained after several hours. New dialysate can then be added to repeat the process.
