Question

Pancreas has

Accepted Answer

The correct answer is: **3. two types of cells exocrine and endocrine.**

### Explanation:

The pancreas is a vital organ in the human body that serves both endocrine and exocrine functions, making it a unique gland with dual roles.

1. **Endocrine Function**: The pancreas contains clusters of cells known as the islets of Langerhans, which are responsible for its endocrine function. These cells secrete hormones directly into the bloodstream. The primary hormones produced include:
   - **Insulin**: Lowers blood glucose levels.
   - **Glucagon**: Raises blood glucose levels.
   - **Somatostatin**: Regulates the secretion of other hormones.

2. **Exocrine Function**: The majority of the pancreas is made up of acinar cells, which are responsible for its exocrine function. These cells produce digestive enzymes (such as amylase, lipase, and proteases) that are secreted into the small intestine via the pancreatic duct. This function is crucial for the digestion of food.

### Why Other Options are Incorrect:

1. **Option 1: only endocrine cells** - This is incorrect because the pancreas has a significant exocrine component that produces digestive enzymes.

2. **Option 2: only exocrine cells** - This is also incorrect as it ignores the important endocrine function of the pancreas, which is essential for regulating blood sugar levels.

3. **Option 4: only one type of cell function both in endocrine as well as exocrine manner** - This is misleading because the pancreas has distinct types of cells (endocrine and exocrine) that perform different functions. They do not function as a single type of cell with dual roles.

In summary, the pancreas has both endocrine and exocrine cells, making option 3 the correct answer.
