Answer

To solve the question "Which of the following system returns the blood from the intestine to the liver?", we can follow these steps:

### Step 1: Understand the Question
The question is asking about a specific system in the body that is responsible for transporting blood from the intestine to the liver.

### Step 2: Analyze the Options
We need to consider the options provided:
1. Renal portal system
2. Hepatic portal system
3. Lymphatic system
4. Systemic circulation

### Step 3: Evaluate Each Option
- **Renal Portal System**: This system is involved in transporting blood to the kidneys, not the liver. Therefore, this option is incorrect.

- **Hepatic Portal System**: This system specifically carries blood from the gastrointestinal tract (including the intestines) to the liver. The term "hepatic" refers to the liver, and "portal" indicates a transport system. This option appears to be correct.

- **Lymphatic System**: This system is responsible for transporting lymph, a clear fluid, and is not directly involved in transporting blood from the intestines to the liver. Thus, this option is incorrect.

- **Systemic Circulation**: This refers to the circulation of oxygenated blood from the heart to the rest of the body and back. It does not specifically address the transport of blood from the intestines to the liver. Therefore, this option is also incorrect.

### Step 4: Conclusion
Based on the evaluations, the correct answer is the **Hepatic Portal System**, as it is the system that returns blood from the intestine to the liver.

### Final Answer
The correct option is **Hepatic Portal System**.
