Hepato-pancreatic duct opens into the duodenum and carries:

Options

A. Bile
B. Pancreatic juice
C. Both bile and pancreatic juice
D. Saliva

Answer

To answer the question regarding what the hepatopancreatic duct carries when it opens into the duodenum, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Hepatopancreatic Duct**:
- The hepatopancreatic duct is a combined duct that carries substances from both the liver and the pancreas.

2. **Identifying the Sources**:
- The liver produces bile, which is important for the digestion and absorption of fats.
- The pancreas produces pancreatic juice, which contains digestive enzymes that help in breaking down carbohydrates, proteins, and fats.

3. **Location of the Duct**:
- The hepatopancreatic duct opens into the duodenum, which is the first part of the small intestine. This is where the digestive juices from both the liver and pancreas are released to aid in digestion.

4. **Analyzing the Options**:
- Option A: Bile - This is related to the liver but does not include pancreatic juice.
- Option B: Pancreatic juice - This is related to the pancreas but does not include bile.
- Option C: Both bile and pancreatic juice - This includes substances from both the liver and pancreas, which is what the hepatopancreatic duct carries.
- Option D: Saliva - This is produced in the mouth and is not relevant to the hepatopancreatic duct.

5. **Conclusion**:
- Since the hepatopancreatic duct carries both bile from the liver and pancreatic juice from the pancreas into the duodenum, the correct answer is **Option C: Both bile and pancreatic juice**.
