The larynx anatomically and functionally is inextricably intertwined with respiratory and digestive physiology and pathophysiology. In the developing human infant, the larynx plays a critical role with respect to swallowing, vocal communication, and active and passive respiration. Dysfunction can be better understood only with a firm understanding of development and function.

This contribution of the otorhinolaryngology perspective describes the fundamental laryngeal developmental and comparative anatomy and physiology for the fetus, the infant, and the adult with respect to the interdependence of swallowing and respiration. It touches upon the related dysfunctions and the use of the assessment tools within the trade. It reflects the interdependence of the anatomical, functional, and clinical relationships.
