The proximal part of stomach in which oesophagus opens is called -

Options

A. Cardiac
B. Pyloric
C. Fundus
D. None

Answer

**Step-by-Step Solution:**

1. **Understanding the Anatomy of the Stomach:**
- The stomach is divided into different regions, each with specific names and functions. The main regions include the fundus, body, and pylorus.

2. **Identifying the Opening of the Esophagus:**
- The esophagus is the tube that connects the throat (pharynx) with the stomach. It opens into the stomach at a specific region.

3. **Recognizing the Proximal Part of the Stomach:**
- The proximal part of the stomach is the area closest to where the esophagus enters. This area is crucial for the initial reception of food.

4. **Identifying the Sphincter:**
- At the junction where the esophagus meets the stomach, there is a sphincter called the gastroesophageal sphincter (also known as the cardiac sphincter). This sphincter regulates the opening between the esophagus and the stomach.

5. **Naming the Specific Region:**
- The specific part of the stomach where the esophagus opens is known as the cardiac region or cardiac portion. This is located just below the gastroesophageal sphincter.

6. **Conclusion:**
- Therefore, the proximal part of the stomach in which the esophagus opens is called the **cardiac region**.

**Final Answer:**
The proximal part of the stomach in which the esophagus opens is called the **cardiac region**.
