<P> There are three types of glands : cardiac glands ( in the proximal part of the stomach ) , fundic ( oxyntic ) glands ( the dominating type of gland ) , and pyloric glands . The cardiac glands mainly contain mucus - producing cells called foveolar cells . The bottom part of the oxyntic glands is dominated by zymogenic ( chief ) cells that produce pepsinogen ( an inactive precursor of the pepsin enzyme ) . Parietal cells , which secrete hydrochloric acid ( HCl ) are scattered in the glands , with most of them in the middle part . The upper part of the glands consist of mucous neck cells ; in this part the dividing cells are seen . The pyloric glands contain mucus - secreting cells . </P>
