Options

B. Oesophagus into stomach
C. Stomach into duodenum
D. Ileum into large intestine

Answer

**Step-by-Step Solution:**

1. **Understanding the Digestive System**: The digestive system consists of various organs that work together to break down food, absorb nutrients, and eliminate waste. It starts from the mouth and ends at the anus.

2. **Identifying the Role of the Pyloric Sphincter**: The pyloric sphincter is a muscular valve located at the lower end of the stomach. Its primary function is to regulate the passage of partially digested food (chyme) from the stomach into the small intestine.

3. **Locating the Pyloric Sphincter**: The pyloric sphincter is situated between the stomach and the duodenum, which is the first part of the small intestine. It controls the opening from the stomach to the duodenum.

4. **Understanding Its Function**: The pyloric sphincter opens to allow small amounts of chyme to enter the duodenum for further digestion and absorption. It prevents the backflow of intestinal contents into the stomach.

5. **Conclusion**: Therefore, the pyloric sphincter regulates the opening of the stomach into the duodenum.
