<P> The cardiac glands are found in the cardia of the stomach which is the part nearest to the heart, enclosing the opening where the esophagus joins to the stomach . Only cardiac glands are found here and they primarily secrete mucus . They are fewer in number than the other gastric glands and are more shallowly positioned in the mucosa . There are two kinds - either simple tubular with short ducts or compound racemose resembling the duodenal Brunner's glands </P> <P> The fundic glands (or oxyntic glands), are found in the fundus and body of the stomach . They are simple almost straight tubes, two or more of which open into a single duct . Oxyntic means acid - secreting and they secrete hydrochloric acid (HCl) and intrinsic factor . </P> <P> The pyloric glands are located in the antrum of the pylorus . They secrete gastrin produced by their G cells . </P> <P> There are millions of gastric pits in the gastric mucosa and their necessary narrowness determines the tubular form of the gastric gland . More than one tube allows for the accommodation of more than one cell type . The form of each gastric gland is similar; they are all said to have a neck region that is closest to the pit entrance and basal regions on the lower parts of the tubes . The epithelium from the gastric mucosa travels into the pit and at the neck the epithelial cells change to short columnar granular cells . These cells almost fill the tube and the remaining lumen is continued as a very fine channel . </P>
