The esophagus is about 8 inches long and is lined by moist pink tissue called mucosa.

Anatomy of the stomach and esophagus. It traverses the muscular portion of the diaphragm esophageal hiatus level of t10 vertebra. The stomach therefore can be considerer as two organs. Unlike the mouth and pharynx the esophagus wall figure 2 contains all four layers of the alimentary canal.

Delivers food from pharynx to stomach. Just before entering the stomach the esophagus passes through the diaphragm. It is intra abdominal for approximately 6cm where it is exposed to the higher intra abdominal pressure.

Microscopic anatomy of the esophagus. The esophagus is a muscular tube connecting the throat pharynx with the stomach. Clinical anatomy of the esophagus stomach.

The mucosal epithelium is a nonkeratinized stratified squamous epithelium. At the junction of the esophagus and stomach this thick abrasion resistant layer changes abruptly to the thin simple columnar epithelium of the stomach which is. Mucosa submucosa muscularis externa and adventitia.

Anatomy of the esophagus the esophagus is a muscular tube about ten inches 25 cm long extending from the hypopharynx to the stomach. In the case of the esophageal sphincter it allows food to pass into the stomach and then tightens up to prevent food from going backwards. Its proximal portiın is designed for storage and digestion and its distal part is adapted to the role of mixing and evacuation.

Describe the course of the esophagus. Food is swallowed and passes through the esophagus to the stomach where the majority of digestion takes place. The esophagus lies posterior to the trachea and the heart and passes through the mediastinum and the hiatus an opening in the diaphragm in its descent from the thoracic to the abdominal cavity.

The following histological features are of interest. The mucosa of the antrum participates in the process of gastric acid secretion by releasing the secretagogue gastrin into the circulation.
