What process uses a machine to remove toxic waste from the body?

The process that uses a machine to remove toxic waste from the body is known as dialysis. This term encompasses both hemodialysis and peritoneal dialysis, which are specific methods used to perform the procedure. Dialysis is a medical treatment that substitutes for the normal kidney function by filtering and purifying the blood when the kidneys can no longer perform these tasks effectively.

Hemodialysis involves circulating the blood through a machine with a dialyzer, where waste products and excess fluids are removed before the clean blood is returned to the body. Peritoneal dialysis, on the other hand, involves instilling a special fluid into the abdomen that absorbs waste products, which are later drained away.

While hemodialysis and peritoneal dialysis are more detailed terms describing specific processes within the broader category of dialysis, the correct answer broadly refers to dialysis as a concept used to eliminate toxic waste from the body. Using the general term captures all methods associated with this vital healthcare function.
