salivary gland ducto-acinar unit
A lobule of a salivary gland consisting of the ducto-acinar unit and the secretory acini together with their contiguous ductal segments, including the intercalated duct and striated duct, together with associated myoepithelial cells, stromal tissue, and vasculature. This structural-functional unit is responsible for the production of primary saliva by the acinar cells and its ionic modification during transit through the ductal segments.
