Anatomical Illustration: Posterior Larynx and Trachea


Final illustration

Background Information

The larynx and trachea are both organs of the respiratory system. The larynx, which is also known as the voice box, controls volume and pitch for the voice. It also serves to prevent food from entering the trachea through the function of the epiglottis. The trachea is the main airway to the lungs and therefore is involved primarily with breathing.

Project Goals

The goal of this project was to provide an educational illustration about the structures of the larynx and trachea. The final deliverable of this illustration was for print in the form of an 8.5" x 11" handout, and also able to be scaled for inclusion in textbook print format.


The main challenge was to portray the small, detailed structures of the larynx in a format that would keep them clear and accessible to the viewer. A posterior view was chosen due to most of the structures of the larynx being only visible from the posterior. Line technique was chosen to depict the organs in order to simplify the structures in a way that would keep them clear without their details being lost by illustrative techniques that might be distracting.
