Parotid gland

Serous secretions are released into the lumen of the acinus and continue into intercalated ducts.  Intercalated ducts are initially lined by simple squamous epithelium which quickly becomes simple cuboidal.  Intercalated ducts are smaller in diameter than the acini.  The point where two acini empty into an intercalated duct is visible in this image.  600x
