Answer 1

churning of the stomach contents.

Step-by-step explanation:

When food is moved to the back of the mouth by the tongue (deglutition), it does not cause the churning of the stomach contents.

The churning of stomach contents occurs when the bolus from the mouth has entered through the lower esophageal sphincter into the stomach. Churning is the mixing of the bolus with digestive juices containing acids and enzymes secreted from the stomach lining.
