An<unk>  is the functional unit in a developing gland. The glands include the salivary and lacrimal glands.<unk> s are secretory sublobular units having a centrally located collecting duct that connects with postcapillary venules; and is a structural-functional unit in the gland. They consist of all the secretory cells that release their products into a single intralobular duct. An<unk>  is composed of: # Intercalated ducts: transport saliva to larger ducts. # Striated ducts: contain a lot of mitochondria responsible for electrolyte and water transport during secretion. Simple, low columnar epithelium line these ducts. # Glandular cells: synthesize glycoproteins.
