One of this organ's membranes is enlarged in Menetrier's disease, while neurotensin and serotonin are secreted by the APUD cells in this organ. Auerbach's plexus enervates one section of this organ, whose inner surface contains folds called rugae. Its submucosa contains Meissner's plexus, and some of its glands contain G cells and the mucous-secreting goblet cells. That same section of this organ contains the chief and parietal cells, and this organ is bounded by the pyloric and cardiac sphincters. The organ accomplishes its function by converting its secreted pepsinogen to pepsin using its secreted hydrochloric acid.  For 10 points, name this digestive organ that food passes through right after the esophagus.
