What are the two main types of dialysis?

The two main types of dialysis are hemodialysis and peritoneal dialysis.

Hemodialysis involves using a machine to filter waste products and excess fluids from the blood. During this process, blood is drawn out of the body, filtered through a dialyzer (artificial kidney), and then returned to the body. This method requires access to the bloodstream, typically through a fistula or catheter. It is commonly performed in a clinical setting, but some patients can be trained to do it at home.

Peritoneal dialysis, on the other hand, utilizes the lining of the abdominal cavity (the peritoneum) to filter blood. A sterile dialysis solution is introduced into the abdomen through a catheter, allowing waste products and extra fluids to pass from the blood vessels in the peritoneal lining into the solution. This method can be performed at home and is often done by the patient themselves, providing more flexibility in terms of timing and frequency.

The other answer choices refer to methods or concepts that do not qualify as primary forms of dialysis. Capillary dialysis is not a recognized form of dialysis, renal dialysis is a general term that can encompass both types, while ultrafiltration is a process that may occur during dialysis but does not represent
