Pancreas is a

Options

A. Sebceous gland
B. Not a gland
C. Gastric gland
D. Composite gland

Answer

**Step-by-Step Solution:**

1. **Identify the Options**: The question provides four options regarding the classification of the pancreas:
- Option 1: Sebaceous gland
- Option 2: Not a gland
- Option 3: Gastric gland
- Option 4: Composite gland

2. **Understand the Definition of Pancreas**: The pancreas is an organ in the body that plays a crucial role in digestion and blood sugar regulation. It has both endocrine and exocrine functions.

3. **Define Composite Gland**: A composite gland is one that has both endocrine and exocrine functions. The pancreas fits this definition as it produces hormones (endocrine function) and digestive enzymes (exocrine function).

4. **Examine the Endocrine Function**: The pancreas contains clusters of cells known as the islets of Langerhans, which are responsible for hormone production. The two main types of cells in these islets are:
- Alpha cells: Secrete glucagon, which raises blood sugar levels.
- Beta cells: Secrete insulin, which lowers blood sugar levels.

5. **Examine the Exocrine Function**: The pancreas produces digestive enzymes that are released into the small intestine to aid in digestion. This is its exocrine function.

6. **Evaluate Each Option**:
- **Sebaceous Gland**: Incorrect, as sebaceous glands secrete oils and are not related to the pancreas.
- **Not a Gland**: Incorrect, since the pancreas is indeed a gland.
- **Gastric Gland**: Incorrect, as gastric glands are found in the stomach and are not related to the pancreas.
- **Composite Gland**: Correct, as the pancreas has both endocrine and exocrine functions.

7. **Conclusion**: The correct answer is that the pancreas is a composite gland.

**Final Answer**: The pancreas is a composite gland.
