The Human Digestive System- Organs and Functions

Content: This is accomplished by periodic contractions (peristalsis). The esophagus is an important connection to the digestive system through the thoracic cavity, which protects the heart and lungs. Two sphincters on either side of the esophagus separate food into small units known as a bolus. D. The Stomach
The stomach is a J-shaped dilated portion of the alimentary tract situated in the epigastric, umbilical, and left hypochondriac regions of the abdominal cavity. The stomach is continuous with the esophagus at the cardiac sphincter and with the duodenum at the pyloric sphincter. It has two curvatures. The lesser curvature is short, lies on the posterior surface of the stomach, and is the downwards continuation of the posterior wall of the esophagus. Just before the pyloric sphincter, it curves upwards to complete the J shape. Where the esophagus joins the stomach the anterior region angles acutely upwards, curves downwards forming the greater curvature then slightly upwards towards the pyloric sphincter. The stomach is divided into three regions:
