Canine Heart Model with Heartworm

Heartworm Disease Reads Very Differently on a Diagram Than in the Heart

Textbook illustrations tend to flatten what's a fairly dramatic physical reality — worms occupying the heart and major vessels in numbers that visibly obstruct normal function. This model makes that concrete for students connecting the parasite lifecycle to the disease it actually causes. A natural fit for parasitology units, cardiac anatomy coursework, and client-education settings where a visual does more than a verbal explanation. As with any anatomical teaching model, it represents disease presentation for education and isn't a substitute for diagnostic imaging or testing in an actual case.
