Question

Quizplus · Accepted Answer

Endocrine glands are characterized by their ability to secrete hormones directly into the bloodstream, rather than through a duct. They consist of highly specialized cells, not non-differentiated cells. Salivary glands are examples of exocrine glands, not endocrine, because they secrete substances through ducts to an external or internal surface, not into the bloodstream.
