These large salivary glands lie outside the mouth but their ducts drain into the mouth. They produce at least a liter of saliva per day. The actual glandular tissue is organized into acini (singular, acinus), which drain into Intercalated ducts , which drain into striated ducts ,( both of which are intralobular i.e. located within the lobule) . Striated ducts lead to the interlobar ducts and, finally, to the main duct. Mucous glands vs. serous glands: A. mucous glands produce strongly hydrophilic glycoproteins called mucins. Once released from the cell, the mucins become hydrated to form mucus, a viscous, protective lubricating gel. The nucleus of mucous cells is at the base of the cell and the cytoplasm is very pale. B. serous glands secrete a protein (enzyme) – rich, watery substance. The cytoplasm stains
