Dialysis意思

Dialysis is a medical procedure that filters and purifies the blood. It is typically used when the kidneys are no longer able to function properly, which can happen in kidney failure. There are two main types of dialysis: hemodialysis and peritoneal dialysis.

Hemodialysis involves using a machine to filter the blood, while peritoneal dialysis uses the lining of the abdomen (peritoneum) to filter the blood. Both types of dialysis help to remove waste products, extra salt, and water from the body, and help to maintain the balance of certain chemicals in the blood.
