Name the process by which blood is cleared of metabolic waste in case of kidney failure

Answer 1

Dialysis is the process it is also known as artificial kidney

Answer 2

Answer:

Dialysis is the process used to remove metabolic waste and excess fluid from blood in case of kidney failure.

It works on the principle of ultra-filtration of fluid and diffusion of solutes across a semi-permeable membrane.

There are two types of dialysis usually practiced: hemodialysis and peritoneal dialysis.

In hemodalysis blood is drawn out of the body into a specialized machine called dialyser for filtration after which it is sent back to the body. The machine is composed of several membranous filters and dialysate.  

In peritoneal dialysis, dialysis fluid or dialysate is pumped into a peritoneal or abdominal cavity. It is left there for some time during which waste product and excess fluid flowing through the blood vessels lining the cavity are diffused out of the blood and transported into the fluid. This fluid is then drained out of the body in a waste container. The process is repeated 3-4 times a day.
