Striated Secretory Duct
Note the striated appearance of the basal aspect of the cells composing this duct (A). Because of this appearance they were initially referred to as "striated" ducts. The cells of striated ducts secrete into the lumen (B), adding to the mucous and/or serous secretions passed along the duct. For this reason, these ducts are now more commonly referred to as "secretory ducts". Note the capillaries (C) lying adjacent to the bases of the secretory duct cells. The secretory cells transport water and electrolytes from the capillaries to the duct lumen.
