B)digestive
C)excretory
D)respiratory

Answer 1

Answer:

C) excretory

Explanation:

The goal of dialysis is to replace the excretory functions of the kidneys when they fail to perform their function of filtering and eliminating toxic substances from the body. There are two types: peritoneal dialysis and hemodialysis.

In peritoneal dialysis, blood is filtered and excess fluid is removed by a natural fluid from the body, the peritoneal membrane (lining of the abdominal cavity, which contains the stomach, spleen, liver and intestines). This dialysis is performed by introducing a catheter into the patient's abdomen.

In hemodialysis (the most common type of dialysis), blood is filtered in a machine that controls the speed, filter pressure and blood volume, acting like an artificial kidney, removing toxins and returning clean blood to the body.

Answer 2

It is c. excretory. the dialysis takes place if the kidneys are not functioning. the kidneys are part of the excretory system.
