Options

A. Liver (A) Intestine (B)
B. Intestine (A) Liver (B)
C. Liver (A) Heart (B)
D. Intestine (A) Heart (B)

Answer

To solve the question regarding the hepatic portal vein, we need to identify the correct points A and B in the context of blood flow.

### Step-by-Step Solution:

1. **Understanding the Hepatic Portal Vein**:
- The hepatic portal vein is a unique blood vessel that carries blood from the digestive organs to the liver. Unlike other veins that transport blood directly to the heart, the hepatic portal vein serves as a conduit from the intestines and other digestive organs to the liver.

2. **Identifying Point A**:
- Point A represents the origin of the blood flow. Since the hepatic portal vein carries blood from the digestive system, specifically from the intestines, we can conclude that A is the **intestine**.

3. **Identifying Point B**:
- Point B represents the destination of the blood flow before it enters systemic circulation. The blood carried by the hepatic portal vein goes to the liver for processing. Therefore, B is the **liver**.

4. **Conclusion**:
- The hepatic portal vein carries blood from the **intestine (A)** to the **liver (B)** before it is delivered to systemic circulation.

### Final Answer:
- A: Intestine
- B: Liver
