An adenomere is the functional unit in a developing gland. The glands include the
salivary The salivary glands in mammals are exocrine glands that produce saliva through a system of ducts. Humans have three paired major salivary glands (parotid, submandibular, and sublingual), as well as hundreds of minor salivary glands. Salivary glan ...

intralobular duct In anatomy and physiology, a duct is a circumscribed channel leading from an exocrine gland or organ. Types of ducts Examples include: Duct system As ducts travel from the acinus which generates the fluid to the target, the ducts become larger ...
. An adenomere 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.
