In frog, the duodenum receives bile from gall bladder and pancreatic juices from the pancreas through a

Options

A. Common bile duct
B. Hepato-pancreatic duct
C. Cystic duct
D. Hepatic duct

Explanation

To answer the question, "In frog, the duodenum receives bile from gall bladder and pancreatic juices from the pancreas through a," we need to follow these steps:

### Step-by-Step Solution:

1. **Identify the Function of the Duodenum**:
- The duodenum is the first part of the small intestine where a significant amount of digestion occurs. It receives digestive juices that help in breaking down food.

2. **Understand the Sources of Digestive Juices**:
- The gall bladder stores bile, which is important for the emulsification of fats.
- The pancreas produces pancreatic juices that contain enzymes necessary for digesting carbohydrates, proteins, and fats.

3. **Determine the Pathway of Bile and Pancreatic Juices**:
- Both bile and pancreatic juices do not enter the duodenum directly from their respective organs. Instead, they travel through specific ducts.

4. **Identify the Ducts Involved**:
- The bile from the gall bladder enters the duodenum through the **common bile duct**.
- The pancreatic juices enter the duodenum through the **pancreatic duct**.

5. **Recognize the Combined Duct**:
- The common bile duct and the pancreatic duct merge to form the **hepatopancreatic duct** (also known as the ampulla of Vater), which opens into the duodenum.

6. **Select the Correct Answer**:
- Given the options provided, the correct answer is the **hepatopancreatic duct**, as it is the duct through which both bile and pancreatic juices enter the duodenum.

### Final Answer:
The duodenum in frogs receives bile from the gall bladder and pancreatic juices from the pancreas through the **hepatopancreatic duct**.
