Accurate subdivisional-surface model of the human heart. Contains six layers:
1. Full human heart with interior.
2. Cutaway human heart with interior, good for medical animation.
3-6. Four valves, one for each chamber.

Full heart matches cutaway heart for easy cross-dissolve. Contains morph maps for the beating of each chamber, opening of the valves, and enlarging of the heart. Also contains texture maps.

Wireframe preview images shown at a subdivision level of 3. Polygon count is total count for full heart, cutaway heart, and valves.
