Upper airway anatomy in order to open the paediatric airway and gain the best view of the laryngeal inlet the oral pharyngeal and tracheal axes must be brought into alignment. The lower airways or lower respiratory tract includes the portion of the larynx below the vocal folds trachea bronchi and bronchioles. The beginning of the respiratory tract the nasal cavity and oropharynx.

Oral cavity consists of mouth palate teeth and tongue. The medical terms for these are the nasopharynx and oropharynxlarynx. With a smaller body size comes an increase in the precision needed to successfully maintain airway patency if any injury or insult to the airway occurs.

The airway of the pediatric patient differs in many ways which impact the anesthesiologists management of the airway.

Upper airway anatomy functions warm filter and humidify air nasal cavity and nasopharynx formed by union of facial bones nasal floor towards ear not eye lined with mucous membranes cilia tissues are delicate vascular adenoids lymph tissue filters bacteria commonly infected.
