Solution
A gland having endocrine as well as exocrine function is pancreas.
Explanation:
The pancreas is a dual-function gland, often called a heterocrine gland or composite gland, because it has both exocrine and endocrine components:
- Exocrine Function: It secretes pancreatic juice containing digestive enzymes (like amylase, trypsin, and lipase) through ducts into the small intestine to help digest food.
- Endocrine Function: It secretes hormones like insulin and glucagon directly into the bloodstream from specialized clusters of cells called the Islets of Langerhans to regulate blood sugar levels.
