Effects of Esophagitis Resulting in Acid Reflux

Description

Anterior thoracic and upper abdominal anatomy is presented in a male figure, centering on the pharynx and esophagus (gullet) as they descend posterior to the trachea toward the stomach. The inflamed esophageal mucosa is emphasized along the distal third, immediately superior to the gastroesophageal junction, where acidic gastric contents reflux proximally into the thoracic esophagus. Superiorly, the pharynx and throat region communicate with the esophageal inlet; inferiorly, the stomach sits left of midline beneath the diaphragm, with adjacent viscera including the small and large intestines and paired kidneys with suprarenal (adrenal) glands. Reflux esophagitis matters because it is the tissue-level correlate of gastroesophageal reflux disease, where impaired lower esophageal sphincter competence and transient relaxations allow repeated acid exposure and mucosal injury. That anatomic relationship becomes clinically concrete during upper endoscopy, where erosions at the Z-line, peptic stricture formation in the distal esophagus, and columnar metaplasia (Barrett esophagus) are assessed, and it also frames anti-reflux operations such as laparoscopic fundoplication and hiatal hernia repair at the esophageal hiatus. Reflux can also present with extraesophageal symptoms when acid reaches the pharynx, driving chronic cough, hoarseness, and laryngopharyngeal irritation. Use this artwork for teaching GERD pathophysiology in medical anatomy, physiology, or gastroenterology modules, and for patient-facing materials explaining why heartburn tracks from the stomach up into the throat. It also suits clinical slide decks on Barrett surveillance, peptic strictures, and perioperative counseling for anti-reflux surgery. Anatomical accuracy verified by SciePro's Medical Advisory Board.
