Identify two types of dialysis.

Dialysis offers two main ways to clean the blood when kidneys can no longer do the job: hemodialysis and peritoneal dialysis. In hemodialysis, blood is taken out of the body, passed through a dialyzer with a semipermeable membrane, and returned as wastes and extra fluid move into the dialysis solution. In peritoneal dialysis, the abdominal lining (the peritoneum) acts as the filter—the dialysis solution is introduced into the abdomen, wastes diffuse into the solution, and then the fluid is drained away. Other terms listed aren’t dialysis types. Ultrafiltration describes fluid removal and is a process used during dialysis rather than a separate modality, and nephrotic therapy is not a dialysis type at all.
