.
They consist of two or three short closed tubes opening into a common duct or mouth.
These tubes are wavy, and are about one-half the length of the duct.
The duct is lined by columnar cells, continuous with the epithelium lining the surface of the mucous membrane
of the stomach, the tubes by shorter and more cubical cell which are finely granular.
The glands contain mucus cells and G cells that secrete gastrin
