Heart animations

Today we dissected sheep hearts in my 6th grade science class. I promised the students I would post links to some of the heart animations that I showed them. Here is a good narrated animation that moves slowly and identifies all the basic chambers, valves, veins and arteries. This is simplifies two dimensional animation depicting blood movement through the heart. And finally this is a fantastic 3d animation that allows you to choose the level of transparency while providing views from multiple perspectives. Some really fantastic animations that demonstrate what an amazing organ the heart really is!
