Answer

To solve the question regarding which vein not belonging to the digestive tract becomes a component part of the hepatic portal system in frogs, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Hepatic Portal System**:
- The hepatic portal system is a network of veins that carries blood from the gastrointestinal tract and spleen to the liver. It is important for processing nutrients and detoxifying substances.

2. **Identify the Options**:
- The options given are:
- Dorsolumbar
- Vesicular
- Gonadial
- Anterior abdominal

3. **Analyze Each Option**:
- **Dorsolumbar Vein**: This vein typically drains the dorsal body wall and is not directly involved in the hepatic portal system.
- **Vesicular Vein**: This vein collects blood from the urinary bladder, which is not part of the digestive tract.
- **Gonadial Vein**: This vein drains the gonads and is also not part of the digestive tract.
- **Anterior Abdominal Vein**: This vein runs along the mid-ventral line and collects blood from the abdominal organs, including the digestive tract.

4. **Determine the Correct Answer**:
- The question asks for a vein that does not belong to the digestive tract but is part of the hepatic portal system. The **anterior abdominal vein** is the only option that fits this description as it collects blood from areas that are not solely digestive in function but still contributes to the hepatic portal system.

5. **Final Answer**:
- The vein not belonging to the digestive tract that becomes a component part of the hepatic portal system in frogs is the **anterior abdominal vein**.
