Options

A. Heart
B. Stomach
C. Kidneys
D. Intestine

Answer

### Step-by-Step Solution:

1. **Understanding the Hepatic Portal Vein**:
- The hepatic portal vein is a major blood vessel that carries blood to the liver. It is important to note that this vein does not carry oxygenated blood; instead, it carries deoxygenated blood rich in nutrients.

2. **Source of Blood**:
- The blood drained by the hepatic portal vein comes from various parts of the digestive system. These include:
- The esophagus
- The stomach
- The intestines (both small and large)
- The pancreas
- The gallbladder

3. **Composition of Blood**:
- The blood collected by the hepatic portal vein is nutrient-rich because it contains the products of digestion from the food we consume. This includes carbohydrates, proteins, and fats that have been broken down in the digestive tract.

4. **Function of the Liver**:
- Once the blood reaches the liver, the liver processes these nutrients. This can involve storing nutrients, converting them into usable forms, and detoxifying harmful substances.

5. **Return to the Heart**:
- After the liver processes the blood, it is returned to the heart through the inferior vena cava, which is a large vein that carries deoxygenated blood from the lower half of the body back to the heart.

6. **Conclusion**:
- Therefore, the hepatic portal vein drains blood to the liver from the digestive organs, and the correct answer to the question is that it drains blood from the digestive tract to the liver.
