Example Question #51 : Organs

The epiglottis is a flap of cartilage that prevents food from entering the __________ when swallowing? 

Possible Answers:

nasopharynx 

diaphragm 

esophagus

larynx

alveoli

Correct answer:

larynx

Explanation:

The epiglottis is a flap of cartilage located at the base of the tongue that prevents food and drink from entering the larynx (and further into the airway). This ensures that food and drink enter the esophagus and gastrointestinal tract. The diaphragm is a muscle involved in respiration. Alveoli are small sacs located in the lungs (at the end of brochioles) that allow for oxygen and carbon dioxide exchange. Nasopharynx is the upper part of the pharynx.
