• Trachea

• Esophagus

• Pharynx

• Larynx

Where is the pharynx located in the airway?

• Below the trachea

• Directly above the vocal cords and epiglottis

• Posterior to the esophagus

• Within the lungs

What is the primary function of the epiglottis during swallowing?

• Filter inhaled air

What is a primary reason for performing endotracheal intubation?

• To improve vocal cord function

• To prevent aspiration (inhalation) of oral contents

• To increase lung capacity

• To diagnose throat infections

How does the laryngoscope assist in opening the airway during intubation?

• By vibrating the vocal cords

• By depressing the tongue and applying pressure to the hypoepiglottic ligament to open the epiglottis

• By creating a vacuum in the trachea

• By stimulating the pharynx
