Which of the following acts as endocrine gland as well as an exocrine gland?

Options

A. Salivary
B. Pancreas
C. Pituitary
D. Parathyroid

Explanation

To determine which gland acts as both an endocrine and exocrine gland, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Definitions**:
- **Endocrine Gland**: This type of gland is ductless and secretes hormones directly into the bloodstream. Hormones are chemical messengers that regulate various bodily functions.
- **Exocrine Gland**: This type of gland has ducts and secretes substances such as enzymes or other fluids directly to specific sites (e.g., saliva, sweat).

2. **Identify Glands**:
- We need to identify glands that can perform both functions (endocrine and exocrine).
- Common examples of glands include the pancreas, salivary glands, pituitary gland, and parathyroid gland.

3. **Analyze Each Gland**:
- **Pancreas**: The pancreas functions as both an endocrine gland (secreting hormones like insulin and glucagon into the bloodstream) and an exocrine gland (producing digestive enzymes that are released into the small intestine).
- **Salivary Glands**: These are purely exocrine glands as they secrete saliva (enzymes) through ducts.
- **Pituitary Gland**: This is purely an endocrine gland as it releases hormones directly into the bloodstream.
- **Parathyroid Gland**: This is also purely an endocrine gland, releasing hormones into the bloodstream.

4. **Conclusion**:
- The only gland that acts as both an endocrine and exocrine gland is the **pancreas**. Therefore, the correct answer is the pancreas.

### Final Answer:
The gland that acts as both an endocrine gland and an exocrine gland is the **pancreas**.
