The University of Pennsylvania Health System provides nearly 200 video animations and explanations of injuries, diseases, and body systems. The animations, like this one of a balloon angioplasty, are concise which makes them good for general reference purposes.
Applications for Education
The medical animation library could be a good resource for biology teachers, health teachers, and teachers of anatomy and physiology.
