Exocrine glands secrete their products into a duct system. The ducts, in turn, transport these secretions to a specific target. Acini are the functional units of the exocrine pancreas. Endocrine glands secrete their products directly into the blood, rather than into a duct system. Islets of Langerhans are the functional units of the endocrine pancreas.
