Question

Quizplus · Accepted Answer

Exocrine glands secrete substances through ducts to an outer body surface or into body cavities, such as the digestive, respiratory, or reproductive tracts. They do not secrete directly into the bloodstream or through absorption through cell membranes as these are functions of endocrine glands. Also, exocrine glands do not secrete into capillaries or vascular tissue, as their secretions are meant to be released externally or into a cavity.
