Q

dialysis

A

the process of removing waste products from the blood when the kidneys are unable to do so. Hemodialysis involves passing the blood through an artificial kidney for filtering out impurities. Peritoneal dialysis involves introducing fluid into the abdomen through a catheter. Through the process of osmosis, this fluid draws waste products out of the capillaries into the abdominal cavity. It is then removed from the abdomen via a catheter.
