Epiglottitis NCLEX Mastery Guide
Epiglottitis
What is epiglottitis? It is the inflammation of the epiglottis. This can lead to an upper airway obstruction.
Anatomy & Physiology of Epiglottis
Anatomy
Location: The epiglottis is a leaf-shaped flap of cartilage located at the base of the tongue, at the entrance of the larynx (voice box). It is situated above the glottis, which is the opening between the vocal cords.
Structure:
- Cartilage: The epiglottis is composed primarily of elastic cartilage, which provides flexibility and strength.
- Covering: It is covered by a mucous membrane that helps protect the underlying cartilage and aids in the movement of the epiglottis.
Physiology
Function: The primary function of the epiglottis is to act as a switch between the trachea and the esophagus to ensure that food and liquids are directed into the esophagus and air is directed into the trachea.
Swallowing Mechanism:
- Resting Position: When not swallowing, the epiglottis stands upright, allowing air to pass freely into the trachea.
- During Swallowing: As you swallow, the larynx elevates, and the epiglottis folds backward to cover the glottis. This action prevents food and liquids from entering the trachea and directs them into the esophagus.
Protection of the Airway: By closing off the trachea during swallowing, the epiglottis protects the airway from aspiration of food and liquids, which could lead to choking or respiratory infections.
