This is the common passage for bile and pancreatic juices

Options

A. Ampulla of Vater
B. Duct of Wirsung
C. Ductus coledochus
D. Duct of Santorini

Answer

### Step-by-Step Solution:

1. **Identify the Structures**: The question refers to the common passage for bile and pancreatic juices. The key structures involved are the pancreas, bile duct, and the sphincter of Oddi.

2. **Understand the Pancreatic Duct**: The pancreatic duct is formed by the merging of smaller ducts from the pancreas, known as the duct of Santorini. This duct carries pancreatic juices that aid in digestion.

3. **Common Bile Duct**: The common bile duct carries bile from the gallbladder and liver. It plays a crucial role in digestion by emulsifying fats.

4. **Combination of Ducts**: The pancreatic duct merges with the common bile duct. This junction is significant because it allows both pancreatic juices and bile to enter the small intestine.

5. **Sphincter of Oddi**: The combined duct opens into the duodenum (the first part of the small intestine) through the sphincter of Oddi. This sphincter controls the flow of bile and pancreatic juices into the intestine.

6. **Ampulla of Vater**: The junction where the pancreatic duct and the common bile duct meet is known as the ampulla of Vater (or hepatopancreatic ampulla). This is the common passage for both bile and pancreatic juices.

7. **Conclusion**: Therefore, the answer to the question is the **ampulla of Vater**.
