Question

Which of the following gland has both exocrine and endocrine parts?

• A. Thyroid
• B. Pituitary
• C. Adrenal
• D. None of the above

Answer 1

Answer: (D)

None of the above

The endocrine system is composed of ductless glands. Endocrine glands secrete hormones. Glands that have ducts are called exocrine glands. The secretions of exocrine glands reach their target by travelling through a duct (tube). The mixed gland is a gland that produces endocrine and exocrine secretions. The pancreas is an example of a mixed gland because it secretes hormones in the circulation, like insulin and glucagon, but it also releases an exocrine secretion, the pancreatic juice. Whereas, thyroid, pituitary and adrenal glands are not having both endocrine and exocrine system.

Therefore, the correct answer is option D.
