The correct Answer is:
### Step-by-Step Solution: 1. **Understanding the Hepato-Pancreatic Duct**: The hepatopancreatic duct, also known as the ampulla of Vater, is a critical structure in the digestive system. It is formed by the union of the bile duct (which carries bile from the liver) and the pancreatic duct (which carries pancreatic juices from the pancreas). 2. **Location**: This duct opens into the duodenum, which is the first part of the small intestine. The duodenum is where a significant amount of digestion occurs, aided by various digestive juices. 3. **Function of the Duct**: The primary function of the hepatopancreatic duct is to transport digestive juices into the duodenum. These juices include: - **Bile**: Produced by the liver, bile helps emulsify fats, making them easier to digest. - **Pancreatic Juice**: Contains various enzymes (such as amylase, lipase, and proteases) that are essential for the digestion of carbohydrates, fats, and proteins. 4. **Conclusion**: Since the hepatopancreatic duct carries both bile and pancreatic juice into the duodenum, the correct answer to the question is that it carries "both bile and pancreatic juice". 5. **Choosing the Correct Option**: Among the given options: - A: Bile (Incorrect, as it does not mention pancreatic juice) - B: Pancreatic Juice (Incorrect, as it does not mention bile) - C: Both bile and pancreatic juice (Correct) - D: Saliva (Incorrect, as it is not related to the hepatopancreatic duct) ### Final Answer: C - Both bile and pancreatic juice. ---
