This 3D model represents the heart of a rabbit (Oryctolagus cuniculus), created with anatomical accuracy for educational and scientific visualization purposes. The model is designed based on standard mammalian cardiac anatomy and is suitable for use in zoology, veterinary science, biology education, and comparative anatomy studies. The heart clearly shows its external morphology, including the atrial and ventricular regions, major blood vessels, and overall realistic shape. The surface detailing and proportions are optimized to closely resemble a real rabbit heart while maintaining clarity for learning and demonstration.
