D. Duct of Santorini

Answer

To answer the question regarding the location of the Sphincter of Boyden, which helps in the filling up of the gall bladder, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Sphincter of Boyden**:
- The Sphincter of Boyden is a muscular structure that regulates the flow of bile into the duodenum from the bile duct. It plays a crucial role in controlling the secretion of bile and pancreatic juices.

2. **Identifying the Relevant Ducts**:
- The question provides several options: ductus choledochus, duct of Wirsung, ampulla of Vater, and duct of Santorini. We need to identify which of these is associated with the Sphincter of Boyden.

3. **Analyzing the Ductus Choledochus**:
- The ductus choledochus is the common bile duct formed by the union of the hepatic duct (from the liver) and the cystic duct (from the gall bladder). It carries bile from the liver and gall bladder to the duodenum.

4. **Locating the Sphincter of Boyden**:
- The Sphincter of Boyden is located at the junction of the ductus choledochus and the ampulla of Vater. It is situated on the posterior side of the hepato-pancreatic ampulla.

5. **Conclusion**:
- Since the Sphincter of Boyden is associated with the ductus choledochus, the correct answer to the question is that the Sphincter of Boyden is present in the **ductus choledochus**.

### Final Answer:
The Sphincter of Boyden, which helps in the filling up of the gall bladder, is present in the **ductus choledochus**.
