Question

The lower esophageal sphincter surrounds the upper opening into the stomach. if this sphincter failed to properly constrict, there might be a problem with _____. view available hint(s) the lower esophageal sphincter surrounds the upper opening into the stomach. if this sphincter failed to properly constrict, there might be a problem with _____. too rapid emptying from the stomach into the small intestine the control of defecation too rapid emptying of the small intestine into the large intestine the movement of swallowed food into the trachea rather than into the esophagus regurgitation of acidic stomach contents into the esophagus, commonly called "heartburn"

Answer 1

The lower esophageal sphincter's failure to constrict properly can lead to regurgitation of stomach acids into the esophagus, causing heartburn or potentially GERD.

Step-by-step explanation:

If the lower esophageal sphincter failed to properly constrict, there might be a problem with regurgitation of acidic stomach contents into the esophagus, commonly called "heartburn". This condition may also lead to gastroesophageal reflux disease (GERD), which involves chronic reflux that can damage the mucous membrane of the esophagus due to the highly acidic stomach contents. The lower esophageal sphincter acts as a valve to prevent the backflow of gastric contents; when it doesn't close properly, it allows for this backflow, causing discomfort and potential damage to the esophageal lining.

Answer 2

The answer is ‘regurgitation of acidic stomach contents into the esophagus, commonly called "heartburn"’. The lower esophageal sphincter (LES) is a bundle of muscles at the low end of the esophagus, where it meets the stomach. When the LES is closed, it prevents acid and stomach contents from traveling backwards from the stomach.
