Chemical messengers which are released into the blood to be transported throughout the body. An (Endocrine/Exocrine) gland is a ductless gland that empties its hormones into the extracellular fluid, from which it enters the blood. Endocrine glands. These glands do not have ducts.
Glands that secrete their products directly into tissue fluids or the blood without ducts are called endocrine glands. Those that secrete their products into ducts that open onto internal or external open surfaces are called exocrine glands.f the duct and secretory portions are of uniform diameter, the gland is tubular. If the secretory cells form a dilated sac at the end of the duct, it is acinar, and if the secretory cells extend uniformly from the duct then form a sac, it is called tubuloacinar.
