Which organ holds food for several hours and then breaks it down into smaller pieces?

• A. Liver
• B. Intestine
• C. Esophagus
• D. Stomach

Answer: (D)

Food sits in the stomach for several hours, where it is both kept for a while and actively broken down into smaller pieces. The stomach muscles churn the contents, mixing them with gastric juice that the stomach lining releases. This gastric juice includes acid, which creates a harsh environment, and enzymes like pepsin that start digesting proteins. The combination of physical grinding and chemical digestion turns the swallowed food into a semi-liquid substance called chyme, which is then released gradually into the small intestine for further digestion and nutrient absorption.

The other organs don’t perform this combination of storage and initial breakdown. The esophagus mainly passes food down to the stomach; the intestine is where most digestion and absorption occur after the stomach; the liver stores bile but not ingested food.
