Answer

To answer the question "Oesophagus opens in which part of the stomach?" we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of the Stomach**:
- The stomach is a J-shaped muscular organ located in the upper part of the abdominal cavity. It has four main parts: cardia, fundus, body, and antrum (or pyloric antrum).

2. **Identify the Parts of the Stomach**:
- **Cardia**: This is the first part of the stomach where the oesophagus opens.
- **Fundus**: This is the rounded upper portion of the stomach.
- **Body**: This is the main central region of the stomach where most digestion occurs.
- **Antrum (Pyloric Antrum)**: This is the lower part of the stomach that leads into the duodenum.

3. **Determine Where the Oesophagus Enters**:
- The oesophagus is the tube that carries food from the mouth to the stomach. It opens into the stomach at the cardia.

4. **Eliminate Incorrect Options**:
- **Pyloric**: This is the last part of the stomach, which opens into the duodenum, so it is incorrect.
- **Fundic**: This is the second part of the stomach, so it is also incorrect.
- **Cecum**: This is not a part of the stomach; it is part of the large intestine, so it is incorrect.

5. **Conclusion**:
- The oesophagus opens into the **cardiac** part of the stomach.

### Final Answer:
The oesophagus opens into the **cardiac** part of the stomach.
