Answer:
Excretory system (Kidney)
The scenario that leads to this question is not correct, however, the question in itself has an answer as stated above.
Explanation:
The kidney is an organ that removes waste and excess fluid in the blood and passes these wastes to the bladder.
If the kidney fails, dialysis is a treatment for kidney failure (not a diabetes treatment as stated in the question).
Dialysis is performed by using a machine to purify the blood.
