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

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

Answer: (A)

The stomach is the organ that holds swallowed food for a while and then breaks it down into smaller pieces. Its muscular walls churn the contents and mix them with gastric juices—acid and the enzyme pepsin—that start chemical digestion, turning the food into a semi-liquid called chyme. The stomach gradually releases chyme into the small intestine for further digestion and nutrient absorption. The esophagus mainly moves food downward, the liver handles bile production, and the intestines finish digestion and absorb nutrients, so the stomach uniquely serves as both a temporary storage site and the site of initial digestion.
