Glucose is carried from digestive tract to liver by

Options

A. Hepatic artery
B. Hepatic portal vein
C. Pulmonary vein
D. None of the above

Answer

To answer the question "Glucose is carried from the digestive tract to the liver by," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Role of the Liver**:
- The liver plays a crucial role in processing nutrients absorbed from the digestive tract. It receives blood that contains these nutrients for further metabolism and storage.

2. **Identifying the Blood Vessels Connected to the Liver**:
- The liver is connected to two main blood vessels: the hepatic artery and the hepatic portal vein.

3. **Function of the Hepatic Artery**:
- The hepatic artery carries oxygenated blood from the aorta to the liver. It supplies the liver with oxygen but does not carry nutrients from the digestive tract.

4. **Function of the Hepatic Portal Vein**:
- The hepatic portal vein carries blood from the gastrointestinal tract, including the small intestine, spleen, and pancreas, directly to the liver. This blood is rich in nutrients, including glucose, which is absorbed from the food we eat.

5. **Absorption of Glucose**:
- Glucose is primarily absorbed in the small intestine (specifically the ileum) after digestion. Once absorbed, it enters the bloodstream and is transported to the liver via the hepatic portal vein.

6. **Conclusion**:
- Since glucose is carried from the digestive tract to the liver by the hepatic portal vein, the correct answer to the question is **hepatic portal vein**.

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