Which of the following diverts food mass away from the opening of the larynx?
Correct answer: B. Epiglottis
- A. Esophageal sphineter
- B. Epiglottis
- C. Respiratory Valve
- D. Soft palate
Explanation
The epiglottis is a flap of tissue located at the base of the tongue, and its main function is to prevent food and liquids from entering the trachea (windpipe) and going down into the lungs. During swallowing, the epiglottis closes off the opening of the larynx, directing the food mass toward the esophagus, which leads to the stomach.
