C. Dialysis
D. Photolysis

Answer

The procedure of cleaning the blood of a person by using a kidney machine is known as **dialysis**.

### Step-by-Step Solution:

1. **Understanding the Function of Kidneys**:
- The kidneys are the main excretory organs in the body. They filter the blood to remove waste products, particularly urea, which is a toxic nitrogenous waste.

2. **Identifying the Need for a Kidney Machine**:
- When the kidneys are not functioning properly, they cannot effectively filter out urea and other waste products from the blood. This can lead to a buildup of toxins in the body.

3. **Introduction to Dialysis**:
- Dialysis is a medical procedure that mimics the function of healthy kidneys. It involves using a machine (the kidney machine) to clean the blood by removing waste products, including urea.

4. **Process of Dialysis**:
- During dialysis, blood is drawn from the patient’s body and passed through a dialysis machine. The machine filters out urea and other waste products before returning the cleaned blood back to the body.

5. **Conclusion**:
- Therefore, the procedure of cleaning the blood using a kidney machine is specifically referred to as **dialysis**.
