Question

The entry of food into the larynx is prevented by

• A. Mitral valve
• B. Diaphragm
• C. Frenulum
• D. Epiglottis

Answer 1

The correct option is D Epiglottis

The cartilage flap called the epiglottis is located in front of the larynx and behind the tongue. The epiglottis moves back and forth to prevent the passage of food and liquids into the lungs. The usual upright position of the epiglottis allows air to flow into the lungs and the larynx. While swallowing, the epiglottis flattens backward to cover the entrance to the larynx and prevent food from entering the lungs and windpipe. The epiglottis returns to its usual position after swallowing. So, the correct answer is option D.
