Question

Quizplus · Accepted Answer

When chyme enters the duodenum, the enterogastric reflex can be activated, which can decrease gastric activity and motility. This is mediated by the release of enterogastrone and other intestinal hormones.

The other statements are incorrect:
A) Enterogastrone actually helps decrease gastric motility.
B) Pepsin is an enzyme produced by the stomach for the purpose of protein digestion, not starch digestion.
D) The mucosa of the stomach is not well-suited for absorption and only a few substances such as alcohol and aspirin are significantly absorbed in the stomach. Most absorption occurs in the small intestine.
