The tongue manipulates food during chewing and helps form a bolus in preparation for swallowing.
Answer
true
Explanation
This statement is **true**. The lecture assigns the tongue a role in manipulating food during chewing and forming the **bolus** before swallowing. This links oral mechanical processing with deglutition: teeth break food down, while tongue movements help gather and position it. The tongue also contains taste receptors, but taste is not the only function described. **Key takeaway:** The tongue helps organize chewed food into a swallowable bolus.\n\n**Glossary:**\n- **Bolus**: A mass of food prepared for swallowing.\n- **Deglutition**: Swallowing.
