Airway anatomy

Airway knowledge links the upper airway, larynx and tracheobronchial tree with ventilation, protection and gas exchange. Supervised practical skills are essential for airway intervention.

Original schematic relationship map for this topic; relationships are organized for study, not intended as an anatomical depiction or a diagnostic algorithm.

Concept 01

Upper airway

Nasal cavity, oral cavity and pharynx conduct inspired air. Upper-airway patency depends on soft-tissue tone, positioning and anatomy.

Concept 02

Larynx

The epiglottis and laryngeal structures help protect the lower airway during swallowing; vocal folds are involved in phonation and glottic opening.

Concept 03

Tracheobronchial tree

The trachea branches into main bronchi and progressively smaller airways, ending in gas-exchanging respiratory units.

Concept 04

Anatomical variation

Age, tissue swelling, facial structure, previous surgery and pathology can affect airway assessment and procedural difficulty.

Education / safety note: This is not an intubation or emergency airway procedure guide. Airway intervention requires current training, equipment and supervision.
