The common passage for bile and pancreatic juice is

Options

A. ampulla of Vater
B. Common Bile Duct
C. duct of Wirsung
D. duct of Santorini

Answer

### Step-by-Step Solution:

1. **Identify the Ducts Involved**:
- The liver produces bile, which is transported through the hepatic duct.
- The gallbladder stores bile and releases it via the cystic duct.
- Both the hepatic duct and cystic duct merge to form the common bile duct.

2. **Understand the Role of the Pancreatic Duct**:
- The pancreas produces pancreatic juice, which is transported through the pancreatic duct.

3. **Common Duct for Bile and Pancreatic Juice**:
- The common bile duct and the pancreatic duct converge at a point known as the hepatopancreatic duct.

4. **Ampulla of Vater**:
- The hepatopancreatic duct opens into the duodenum at a dilated region called the ampulla of Vater (or ampulla of Oddi).
- This structure serves as the common passage for both bile (from the liver) and pancreatic juice (from the pancreas).

5. **Regulation of Secretion**:
- The flow of bile and pancreatic juice into the duodenum is regulated by the sphincter of Oddi.

6. **Conclusion**:
- Therefore, the common passage for bile and pancreatic juice is the ampulla of Vater.

### Final Answer:
The common passage for bile and pancreatic juice is the **ampulla of Vater**.
