For 10 points, name this J-shaped organ that comes directly after the esophagus, an organ that digests food.
A fold of the peritoneum descending below this organ is known as the greater omentum. Although it has nothing to do with the heart, cells that secrete mucus make up the majority of this organ's cardiac region, which lies inferior to this organ's fundic region. Overproduction of one of this organ's secretions leads to Zoellinger-Ellison syndrome, and the walls of this organ are damaged in infections of H Pylori. The chief cells of this organ secrete pepsinogen, which becomes pepsin when it mixes with the secretion of the parietal cells. That secretion of this organ, hydrochloric acid, is regulated by the hormone gastrin. For 10 points, name this J-shaped organ that comes directly after the esophagus, an organ that digests food.
