What muscular organ aids in chewing and swallowing food?

• A. Esophagus
• B. Tongue
• C. Larynx
• D. Pharynx

Answer: (B)

The tongue is the muscular organ responsible for handling food in the mouth during chewing and starting the swallowing process. Its intrinsic and extrinsic muscles allow it to move in multiple directions, so it can position food between the teeth, mix it with saliva to form a cohesive bolus, and shape and compress the bolus for efficient grinding. When chewing ends, the tongue pushes the bolus upward against the palate and toward the back of the mouth, helping initiate swallowing. While the pharynx and esophagus come into play after the oral phase to move food down to the stomach, and the larynx helps protect the airway during swallowing, the tongue is the primary structure that manipulates food and kickstarts the swallowing process.
