Question

Identify the correct combination.

• A. Pancreas – Heterocrine glands
• B. Hypothalamus – Exocrine glands
• C. Sweat glands – Unicellular glands
• D. Mammary gland – Endocrine glands

Answer 1

The correct option is A Pancreas – Heterocrine glands

Heterocrine glands are those that perform the functions of both exocrine (with ducts) and endocrine (ductless) glands. Pancreas are considered to be heterocrine glands. Pancreatic acini produce pancreatic juice which is considered to be the richest digestive juice. They release their secretion into pancreatic duct, hence are exocrine. Islets of Langerhans of pancreas produce hormones like insulin and glucagon which are released directly into bloodstream. Hence endocrine function.

Hypothalamus is an endocrine gland whereas mammary glands and sweat glands are exocrine glands.

Goblet cells of the alimentary canals are unicellular glands that produce mucus.
