The pancreas is called a mixed gland.
Why is the Pancreas a Mixed Gland?
The pancreas is unique because it functions as both an exocrine and an endocrine gland. This dual role earns it the designation of a "mixed gland."
-
Exocrine Function: The pancreas produces digestive enzymes (like amylase, lipase, and protease) that are released into the small intestine via ducts. These enzymes break down food, aiding in digestion. This is the exocrine function—secreting substances through ducts.
-
Endocrine Function: The pancreas also contains specialized cells called islets of Langerhans. These islets produce hormones, such as insulin and glucagon, which are released directly into the bloodstream. These hormones regulate blood sugar levels. This is the endocrine function—secreting hormones directly into the bloodstream.
Several sources corroborate this:
- Byju's states that the pancreas "works as both an exocrine and endocrine gland."https://byjus.com/question-answer/which-gland-is-known-as-mixed-gland/
- Testbook confirms that the pancreas is a "mixed gland having both endocrine and exocrine functions." https://testbook.com/question-answer/which-of-the-following-is-known-as-mixed-gland--6380fb5720cb0116cd17623f
- Socratic explains that the pancreas is a mixed gland because it "performs functions of both exocrine and endocrine glands." https://socratic.org/questions/why-is-the-pancreas-known-as-a-mixed-gland
While other glands might have multiple secretions (like the salivary glands, which are described as mixed in some contexts), the pancreas's distinct dual roles as both an exocrine and endocrine gland solidify its classification as a mixed gland.
