Which of the Following is an Exocrine Gland

Question

Which of the following is an exocrine gland?
A) parathyroid
B) salivary glands
C) thymus
D) testes
E) adrenal gland

Accepted Answer

Exocrine glands secrete substances such as sweat, mucus, and digestive enzymes through ducts to external surfaces or body cavities. The salivary glands secrete saliva through ducts into the mouth, making them an exocrine gland. The parathyroid and thymus glands are endocrine glands, as they secrete hormones directly into the bloodstream. The testes and adrenal gland are also endocrine glands, although the testes do have a small exocrine component in their ability to secrete sperm through ducts.
