Glucose from the digestive tract is transported to liver by :-

Options

A. Hepatic vein
B. Portal vein
C. Renal vein
D. Aorta

Answer

To determine how glucose from the digestive tract is transported to the liver, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Glucose Absorption**:
- Glucose is a simple sugar that is produced from the digestion of carbohydrates. It is primarily absorbed in the small intestine after food consumption.

2. **Location of Absorption**:
- The absorption of glucose mainly occurs in the jejunum, which is a part of the small intestine.

3. **Transport Mechanism**:
- Once glucose is absorbed into the bloodstream from the small intestine, it enters the circulatory system.

4. **Pathway to the Liver**:
- The blood from the small intestine does not go directly to the heart. Instead, it is routed through a specific vein that carries nutrient-rich blood to the liver.

5. **Identifying the Correct Vein**:
- The vein responsible for transporting blood (and thus glucose) from the digestive tract to the liver is the **portal vein**. This vein collects blood from the gastrointestinal tract and spleen and directs it to the liver for processing.

6. **Conclusion**:
- Therefore, the correct answer to the question is that glucose from the digestive tract is transported to the liver by the **portal vein**.

### Final Answer:
Glucose from the digestive tract is transported to the liver by the **portal vein**.
