Final answer:
The main difference between hemodialysis and peritoneal dialysis is the location at which it is usually performed.
Step-by-step explanation:
The main difference between hemodialysis and peritoneal dialysis is that hemodialysis is usually done at a special facility and peritoneal dialysis is usually done at home.
Hemodialysis is a medical procedure in which blood is filtered externally through a machine. It involves passing the patient's blood through a dialysis machine that filters waste products and excess water before returning the cleaned blood to the body. Hemodialysis is typically done on an outpatient basis in a hospital or special dialysis clinic.
In contrast, peritoneal dialysis is a procedure that filters waste products and excess fluids from the blood using the peritoneum, a membrane lining the abdominal cavity. It is usually performed at home by the patient or a caregiver.
