Question

While swallowing, which part diverts food mass away from the opening of larynx ?

• A. Pharynx
• B. Trachea
• C. Epiglottis
• D. Alveolus

Answer 1

The Correct Option is C

To solve the problem, we need to determine which part of the body diverts food away from the opening of the larynx (voice box) during swallowing. This involves understanding the anatomy and function of the structures involved in swallowing.

1. Understanding Swallowing Mechanism:
Swallowing is a complex process that ensures food travels safely from the mouth to the esophagus while preventing it from entering the respiratory tract (lungs). The larynx has an opening called the glottis, which must be protected during swallowing to prevent choking.

2. Evaluating the Options:
Let us evaluate each option provided:

1. Pharynx: The pharynx is a muscular tube that serves as a common passageway for both air and food. It connects the nasal cavity, oral cavity, and larynx to the esophagus. While the pharynx is involved in swallowing, it does not directly divert food away from the larynx. Therefore, this option is incorrect.
2. Trachea: The trachea (windpipe) is the tube that carries air to and from the lungs. It is located below the larynx and is not involved in diverting food away from the larynx. Therefore, this option is incorrect.
3. Epiglottis: The epiglottis is a flap of tissue located at the base of the tongue. During swallowing, the epiglottis folds backward to cover the opening of the larynx (glottis), effectively sealing it off. This prevents food or liquid from entering the respiratory tract and ensures that the food mass is directed into the esophagus. This is the correct answer.
4. Alveolus: Alveoli are tiny air sacs in the lungs where gas exchange occurs. They are not involved in the swallowing mechanism and do not divert food away from the larynx. Therefore, this option is incorrect.

3. Conclusion:
The epiglottis plays a crucial role in protecting the larynx during swallowing by covering the glottis and diverting food away from the respiratory tract.

Final Answer: (C) Epiglottis
