Which feature characterizes the human stomach?

Question

Quizplus · Accepted Answer

Smooth muscle contractions of the stomach cause small amounts of chyme to squirt through the open pyloric sphincter into the small intestine. This is known as gastric emptying. Option A is incorrect because the average time for gastric emptying varies from person to person but is typically around 2-6 hours. Option B is incorrect because lipases are enzymes that break down fats, not a mixture of lipases and partly digested food. Option C is incorrect because absorption of alcohol, caffeine, and aspirin occurs in the stomach as well as in the small intestine. Option E is incorrect because the stomach does not receive digestive enzymes from the pancreas, but rather secretes its own digestive enzymes such as pepsinogen and gastric lipase.
