Question

Which of the following has both endocrine and exocrine activity?
A) the pituitary gland
B) parathyroid glands
C) salivary glands
D) the pancreas
E) adrenal glands

Accepted Answer

The pancreas has both endocrine and exocrine functions. The exocrine function involves the secretion of digestive enzymes into the small intestine to aid in digestion, while the endocrine function involves the secretion of hormones, such as insulin and glucagon, into the bloodstream to regulate blood sugar levels. The other options listed only have either endocrine or exocrine activity, but not both.
