Question

multiple choice question
sometimes while eating, food particles enter the larynx and cause severe coughing. this occurs when the ______ fails to close off the larynx.
o hyoid bone
o epiglottis
o tongue
o uvula

Explanation:

The epiglottis is a flap of tissue that covers the larynx (windpipe) during swallowing to prevent food and liquids from entering the trachea. If it fails to close properly, food particles can enter the larynx, causing coughing. The hyoid bone is a U - shaped bone in the neck that supports the tongue and larynx but is not directly involved in closing the larynx. The tongue is involved in chewing, tasting, and swallowing but does not close the larynx. The uvula helps in speech and prevents food from entering the nasal cavity, not the larynx.

Answer:

epiglottis
