6. Which organ helps break down food by grinding it with your teeth?

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

Correct answer: D

The teeth in the mouth play a crucial role in this initial stage of digestion by physically breaking down food into smaller particles. The other options listed do not directly participate in the mechanical breakdown of food through chewing.
