Pancreas has double role of

Options

A. Storage and digestion
B. Digestion and absorpton
C. Digestion and endocrine activity
D. None of the above

Answer

### Step-by-Step Solution:

1. **Understanding the Pancreas**: The pancreas is a vital organ in the human body that plays a crucial role in both digestion and hormone regulation.

2. **Identifying the Roles**: The pancreas has two primary functions:
- **Exocrine Function**: This involves the secretion of digestive enzymes that aid in the digestion of food.
- **Endocrine Function**: This involves the secretion of hormones that regulate blood sugar levels.

3. **Exocrine Function**:
- The pancreas contains **acinar cells** that produce pancreatic juice.
- This juice contains several important enzymes such as:
- **Trypsin**: A protease that digests proteins.
- **Chymotrypsin**: Another protease that also digests proteins.
- **Carboxypeptidase**: Helps in protein digestion.
- **Lipase**: Digests fats.
- **Nucleases**: Digests nucleic acids.
- These enzymes are crucial for breaking down proteins, fats, and nucleic acids in the food we consume.

4. **Endocrine Function**:
- The pancreas contains clusters of cells known as the **Islets of Langerhans**, which have different types of cells:
- **Alpha cells**: Secrete **insulin**, which lowers blood sugar levels.
- **Beta cells**: Secrete **glucagon**, which raises blood sugar levels.
- **Delta cells**: Secrete **somatostatin**, which inhibits the effects of insulin and glucagon.
- These hormones play a significant role in maintaining glucose homeostasis in the body.

5. **Conclusion**: Based on the functions described:
- The pancreas does not have a role in storage.
- Digestion and absorption are not both functions of the pancreas; absorption primarily occurs in the small intestine.
- Therefore, the correct answer is that the pancreas has a double role of **digestion and endocrine activity**.

### Final Answer:
The pancreas has a double role of **digestion and endocrine activity**.
