Question

A client's stomach lacks the ability to effectively churn the food bolus presented after eating. Which layer of the gastrointestinal tract is likely responsible for this problem?

a. The mesenteric layer of the nerve plexus layer
b. The stomach's adventitia layer
c. The mucosal layer of the stomach
d. The oblique layer of the muscularis mucosa layer

Answer 1

The problem with effective churning of food in the stomach is likely related to the muscularis layer, specifically the oblique muscle layer, which is responsible for the stomach's ability to churn food.

Step-by-step explanation:

The ability of the stomach to churn food is primarily due to the actions of the stomach muscles. The layer responsible for churning the food bolus in the stomach is the muscularis layer, which includes the oblique muscle layer. This layer of the gastrointestinal tract is equipped with an additional inner oblique muscle that allows for the vigorous churning and mixing of food required for digestion. The lack of effective churning could indicate a problem within the muscularis layer, particularly within the oblique muscle layer.
