Multiple Choice

What is the primary function of the epiglottis in the respiratory system?

To facilitate the exchange of oxygen and carbon dioxide in the alveoli

To produce mucus that traps dust and pathogens

To prevent food and liquid from entering the trachea during swallowing

To regulate the airflow into the bronchi

Verified step by step guidance

Understand the location and structure of the epiglottis: The epiglottis is a flap of tissue located at the entrance of the larynx, which is part of the respiratory system.

Identify the role of the epiglottis during swallowing: When swallowing, the epiglottis acts as a switch to cover the trachea, preventing food and liquid from entering the airway.

Differentiate between the functions of the epiglottis and other respiratory structures: Unlike the alveoli, which are involved in gas exchange, the epiglottis does not facilitate oxygen and carbon dioxide exchange.

Clarify the protective function of the epiglottis: Its primary function is to ensure that the airway remains clear of food and liquid, which could cause choking or respiratory infections if they enter the trachea.

Summarize the importance of the epiglottis in the respiratory system: By preventing aspiration, the epiglottis plays a crucial role in maintaining a clear airway and protecting the respiratory system during the process of swallowing.
