Question

A brief description of dialysis

Answer 1

Dear Student
The history of dialysis dates back to the 1940s. The first type of dialyzer, then called the artificial kidney, was built in 1943 by Dutch physician Willem Kolff.
Dialysis: 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 withkidney 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 done by using a special fluid called dialysate. Dialysate, a mixture of pure water and chemicals, is carefully controlled to pull wastes out of your blood without removing substances from body needs. A semipermeable membrane (one with microscopic holes that allow only certain types of particles to pass through) keeps the blood apart from the dialysate. This membrane lets the wastes and fluid in blood flow through into the dialysate. The blood cells and larger molecules, like protein that are need, cannot fit through the holes.
