Respiratory tract structures
| Term | Definition |
|---|---|
| Pharynx | Conducts air between nasal cavity and larynx |
| Larynx | Conducts air between the pharynx and trachea Prevents food from entering lower airways Vocalization Ciliary escalator removes contaminants |
| Epiglottis | Flexes during swallowing to cover larynx and prevent food from entering lower airways |
| Vestibule | Conducts air between pharynx and vestibular folds |
| Vestibular folds (false vocal folds) | Slow contaminants dripping toward lower airways |
| Ventricle (laryngeal ventricle) | Conducts air between mucosal folds of larynx |
| Vocal folds (true vocal folds or vocal cords) | Prevent contaminants from entering lower airways Produce vibrations when pulled together during expiration (vocalization) |
| Infraglottic cavity | Conducts air between vocal folds and trachea |
| Tonsils | Immune protection of respiratory and digestive mucosa |
| Laryngopharynx | Conducts air between oropharynx and larynx |
| Oropharynx | Conducts air between nasopharynx and/or oral cavity and laryngopharynx |
| Nasopharynx | Conducts air between posterior nares and oropharynx |
