The correct Answer is:
**Step-by-Step Solution:** 1. **Identify the Structure of the Stomach**: The stomach is a muscular organ that aids in digestion. It has different regions, one of which is the pyloric region, located at the lower end of the stomach. 2. **Understand the Connection to the Duodenum**: The pyloric region of the stomach connects to the small intestine, specifically the first part called the duodenum. 3. **Locate the Junction**: At the junction where the pyloric region meets the duodenum, there is a narrow opening that regulates the passage of food from the stomach into the duodenum. 4. **Identify the Guarding Structure**: This opening is controlled by a muscular valve known as the pyloric sphincter. The pyloric sphincter functions to open and close, allowing the contents of the stomach to enter the duodenum in a regulated manner. 5. **Conclusion**: Therefore, the opening of the stomach into the duodenum is guarded by the pyloric sphincter. **Final Answer**: The opening of the stomach into the duodenum is guarded by the pyloric sphincter. ---
