The gastric glands of stomach are examples of:

Options

A. simple tubular glands
B. simple branched tubular glands
C. compound tubular glands
D. compound tubular, alveolar glands

Answer

To determine the type of glands that gastric glands in the stomach represent, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Function of Gastric Glands**: Gastric glands are responsible for secreting gastric juice, which contains hydrochloric acid and digestive enzymes. This is crucial for digestion in the stomach.

2. **Understand Gland Types**: Familiarize yourself with the different types of glands:
- **Simple Tubular Glands**: These have a single, straight duct and are typically found in the small intestine.
- **Simple Branched Tubular Glands**: These have a branched structure but a single duct opening. They are characterized by clusters of secretory cells.
- **Compound Tubular Glands**: These have multiple ducts and are found in glands such as mucous glands in the mouth.
- **Compound Tubular Alveolar Glands**: These have both tubular and alveolar (sac-like) structures and are found in glands of the respiratory passages.

3. **Analyze the Structure of Gastric Glands**: Gastric glands have a single duct that opens into the stomach and consist of branched clusters of secretory cells. This matches the description of simple branched tubular glands.

4. **Conclusion**: Based on the structure and function of the gastric glands, we conclude that they are classified as simple branched tubular glands.

5. **Final Answer**: The gastric glands of the stomach are examples of **simple branched tubular glands**.
