Question

The structure which prevents the entry of food into respiratory is called

• A. Larynx
• B. Glottis
• C. Pharynx
• D. Epiglottis

Answer 1

The correct option is D

Epiglottis

The correct option is D:

1. Larynx is a part of the respiratory system which is a hollow tube made of cartilages that lets air pass from throat (pharynx) to the trachea.
2. Glottis is the middle part of the larynx where vocal cords are found.
3. At the superior end of the larynx in the throat, there is a structure called epiglottis which is a flexible flap.
4. To permit air to enter the airway to the lungs and allow food to pass into the gastrointestinal tract, epiglottis acts as a switch between the larynx and the esophagus.
5. The body is protected from choking on food that would normally obstruct the airway by the epiglottis.
6. Hence, the right answer is epiglottis.
