Across
- 1. Folds- Structures in the larynx that vibrate to produce sound.
- 3. Sinuses – Air-filled spaces in skull bones that lighten the skull and affect voice resonance.
- 5. Respiration – Exchange of gases between alveoli and the blood.
- 8. Membrane – Thin barrier between alveoli and capillaries where diffusion of O₂ and CO₂ happens.
- 12. – Smallest conducting airways that lead toward the alveolar ducts.
- 13. Cavity – The chamber inside the nose where air is warmed, filtered, and humidified.
- 14. – A flap of cartilage that covers the glottis during swallowing to prevent choking.
Down
- 2. – Tiny air sacs where gas exchange occurs.
- 3. – The throat a shared passageway for both air and food.

- 6. – Voice box that houses the vocal cords and prevents food from entering the airway.
- 7. – The dome-shaped muscle essential for inspiration.
- 9. – The windpipe supported by C-shaped cartilage rings.
