Anatomy Of Stomach And Esophagus

The esophagus is a food passageway from the pharynx to the stomach see figure 1. The stomach therefore can be considerer as two organs.

Human Anatomy Digestive System

The mucosa of the antrum participates in the process of gastric acid secretion by releasing the secretagogue gastrin into the circulation.

Anatomy of stomach and esophagus. The esophagus is situated in front of the spine and behind the heart and trachea windpipe. Delivers food from pharynx to stomach. Food is swallowed and passes through the esophagus to the stomach where the majority of digestion takes place.

It passes through the diaphragm before emptying into the stomach. The esophagus is about 8 inches long and is lined by moist pink tissue called mucosa. The esophagus is a long fibromuscular tube that runs in the thoracic cavity and connects the pharynx with the stomach.

The upper and lower parts of the esophagus contain muscular sphincters. It forms an important piece of the gastrointestinal tract and functions as the conduit for food and liquids that have been swallowed into the pharynx to reach the stomach. The esophagus begins at the base of the laryngopharynx and descends posterior to the trachea passing through the mediastinum.

The esophagus is a muscular tube connecting the throat pharynx with the stomach. The upper esophageal sphincter ues lies at the top of the esophagus. Anatomy of the esophagus the esophagus is a muscular tube about ten inches 25 cm long extending from the hypopharynx to the stomach.

Stomach your stomach is a c shaped digestive organ. It runs from below the cricoid cartilage at the level of c6 to the cardiac. The esophagus runs behind the windpipe trachea and heart and in front of the spine.

The esophagus a straight collapsible muscular tube about 25 cm 10 in long that lies posterior to the trachea. It traverses the muscular portion of the diaphragm esophageal hiatus level of t10 vertebra. Clinical anatomy of the esophagus stomach.

Describe the course of the esophagus. Just before entering the stomach the esophagus passes through the diaphragm. The esophagus is a long thin and muscular tube that connects the pharynx throat to the stomach.

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. It is intra abdominal for approximately 6cm where it is exposed to the higher intra abdominal pressure. 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.
