). This muscular tunic transitions to smooth muscle in the abdomen, with a stomach-like columnar epithelium; its mucosae form short, thick projections into the lumen, not visible in the former portions. The transition from stratified squamous epithelium to simple columnar epithelium is gradual and occurs at the esophageal hiatus of the diaphragm. The stomach is shaped like a bagpipe with small, rounded projections on its outer surface which appear as a series of incomplete subcompartments on the inside. The gastric mucosa has elongated projections, suggesting a high capacity for expansion and storage. Cardiac and pyloric mucosae are similar, with scant, long projections, whereas fundic mucosae are uniform and median in length. Due to the pronounced bagpipe shape of the stomach, the cardia and pylorus are very close, particularly when the stomach is empty (
