Pancreas called a dual nature? Why?
Answers
Answer:
Pancreas is called dual natured because it acts as both an endocrine (which secretes directly into blood stream) and exocrine (which secretes in specific areas through a duct) glands. The endocrine part of pancreas secretes glucagon and insulin, both of which helps in maintaining the normal blood glucose level. The exocrine part secretes pancreatic amylase responsible for breakdown of food.

Answer:
The pancreas is dual function in that it's both an endocrine and exocrine gland. As well as secreting hormones into blood (endocrine),it also secretes enzymes through ducts to the digestive system (exocrine).
It is located behind the stomach and surrounded by spleen, liver and small intestine. It is a vital part of the digestive system and is responsible for regulating blood sugar levels.
The pancreas secretes digestive enzymes such as proteases, amylase and lipase into the duodenum. These enzymes help in digesting proteins, sugars and fat respectively. Islets of Langerhans are embedded in the pancreas that secretes hormones such as insulin and glucagon into the blood.
