Ducts: ▪ Intercalated ducts diameter: thinnest wall: simple low cuboidal epithelium
Striated duct (secretory duct v wall: simple columnar epithelium; the nucleus is near the cell apex, cytoplasm is acidophilic, has basal striations EM: the basal striations created by membrane infolding and mitochondia reabsorbing sodium and excreting potassium; transport water and ions
