In the rabbit's respiratory pathway, which structure prevents food from entering the trachea?
AEpiglottis
BLarynx
CBronchus
DAlveolus
Answer & Solution
Correct answer: A. Epiglottis
1. Air passes from the pharynx through the glottis into the trachea.
2. The epiglottis is a flap that guards this opening.
3. It prevents food from entering the trachea through the glottis.
4. The larynx is the voice box producing sound, not a food guard, so it is the trap.
