WCLN - The Pharynx and the Esophagus

 Peristalsis occurs as alternating waves of contraction and relaxation and serves to propel food down the tract. 

 The main propulsive force that occurs in the majority of the alimentary canal is called __________. 

 The gastroesophageal sphincter is the junction between stomach (<i>gastro-</i>) and esophagus. A loose gastroesophageal sphincter can cause heartburn or acid reflux. 

 During deglutition, the bolus passes into the stomach from the esophagus through the __________. 

Swallowing Animations

 The gastroesophageal (cardiac) sphincter is located at the junction of the esophagus and stomach. If the gastroesophageal sphincter is weak, the chyme from the stomach can reflux into the esophagus and cause heartburn. 

 A weak gastroesophageal (cardiac) sphincter can result in heartburn.
