Parotid gland
Intralobular ducts exit the lobules to form interlobular ducts located in the dense irregular connective tissue surrounding the lobules. As these ducts increase in diameter, their epithelium frequently becomes stratified columnar and eventually transitions to the stratified squamous epithelium of the vestibule into which they will empty. 100x
