Correct option is C
The correct answer is (c) Kidneys.
· Dialysis is a medical procedure used when a patient’s kidneys are unable to function properly.
· The kidneys normally filter waste products and excess fluids from the blood.
· When they fail to do so, dialysis artificially performs this function by removing waste and maintaining the balance of electrolytes and fluids in the body.
· It is commonly used in patients with chronic kidney disease or acute kidney failure.
Additional Information:
· Lungs : Problems with the lungs may require oxygen therapy or ventilation support, not dialysis.
· Liver : Liver failure might require treatments like liver transplantation but not dialysis.
· Heart : Heart issues may need procedures like stenting, bypass surgery, or pacemakers, but dialysis is unrelated.
