Correct Answer is B

Explanation

A. Nothing, it's just a pass through to the next structure: The stomach plays a critical role in digestion through mixing and secretion of gastric juices.

B. Gastric juices mix with the food and the stomach muscles squeeze it: This process forms chyme through mechanical (squeezing) and chemical (acid/enzymes) digestion.

C. The food moves quickly into the small intestine: Food stays in the stomach for a period of time for processing before gradually passing into the small intestine.

D. The food is completely digested and is absorbed by tiny blood vessels in the walls of the stomach: Most digestion and nutrient absorption occur in the small intestine, not the stomach.
