Final answer:
Hemodialysis and peritoneal dialysis are the two types of dialysis.
Step-by-step explanation:
Hemodialysis and peritoneal dialysis are the two types of dialysis. In hemodialysis, a patient's blood is passed through a dialysis machine where waste molecules, such as urea, are removed through a semipermeable membrane. Peritoneal dialysis, on the other hand, uses the patient's peritoneum as the dialyzing membrane, with dialysate flowing into the peritoneal cavity and waste products being removed through diffusion.
