Structure of compound glands
This portion of a single lobule consists entirely of acini. The ducts draining the acini gradually increase in diameter and their lining epithelia gently transition from low cuboidal to columnar. These ducts, called intralobular, are located within the lobule, surrounded by secretory they units. They join to form interlobular ducts that exit the lobule surrounded by connective tissue and are lined by a stratified columnar epithelium. 100x
