The pancreas is regarded as a dual gland because it has both endocrine and exocrine functions.

1. **Endocrine Function**: The endocrine component of the pancreas consists of clusters of cells known as the islets of Langerhans. These cells produce hormones that are released 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 and helps control the rate of digestion.

2. **Exocrine Function**: The exocrine part of the pancreas produces digestive enzymes and bicarbonate that are secreted into the small intestine through the pancreatic duct. These enzymes include:
- Amylase: Breaks down carbohydrates.
- Lipase: Breaks down fats.
- Proteases (like trypsin and chymotrypsin): Break down proteins.

The combination of these two distinct types of functions—hormonal regulation of glucose metabolism (endocrine) and digestion (exocrine)—is what categorizes the pancreas as a dual gland. This complexity is essential for maintaining both metabolic homeostasis and proper digestion.
