ISD principles for a dry technical topic

I am working on a web program which discusses the anatomy of swallowing and how it applies to a clinical or instrumental exam. It has been a challenge not to make the program feel like the reading of a text book. Weaving pratical information throughout has been critical. But I'm thinking that some sort of interesting cartoon narrative throughout might make this dry topic a little more entertaining.
