Male Stomach Anterior Section Reflux Esophagitis

Description

An anterior cross section of the male stomach and distal esophagus showing the anatomy of gastroesophageal reflux. Gastric acid refluxes upward through a weakened lower esophageal sphincter, contacting the squamous epithelium of the esophagus. The distal esophageal mucosa shows the inflammatory changes of reflux esophagitis. GERD affects a significant portion of the adult population. Chronic acid exposure damages the esophageal lining and can lead to erosive esophagitis, stricture formation, and Barrett's esophagus, a metaplastic change that carries an increased risk of esophageal adenocarcinoma. The model supports patient education about reflux, gastroenterology teaching, and clinical training. Reviewed by a medical advisory board. Ready for rendering, real-time, and 3D printing.
