part of part of organ subunit saliva-secreting gland lobule salivary gland ducto-acinar unit https://github.com/obophenotype/uberon/issues/3657 salivon Also known as the "salivon" in classical salivary physiology literature. The three major salivary glands (parotid, submandibular, sublingual) contain gland-specific variants of this unit that differ in acinar cell composition (serous vs. mucous vs. mixed). 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. salivary gland ducto-acinar UBERON:8000010
