Answer 1

Answer:

sphincters

Stomach

In this process, ring-like sphincters occurs pushing the contents into the next area, which is stomach . This process is similar to squeezing toothpaste out of a tube.

Explanation:

Ring-like muscles called sphincters form valves in the digestive system. The gastro-esophageal sphincter (or cardiac sphincter) is located at the stomach end of the esophagus. In response to swallowing and the pressure exerted by the bolus of food, this sphincter opens, and the bolus enters the stomach. When there is no swallowing action, this sphincter is shut and prevents the contents of the stomach from traveling up the esophagus. Acid reflux or “heartburn” occurs when the acidic digestive juices escape into the esophagus.
