so many educational film be nothing more than mind numbing drudgery and save only by the fact that mst3k mock them ( why study industrial art . come to mind ) . hemo the magnificent be actually quite well do . it all about blood and the heart and and the circulatory system . i admit that i do not remember everything from it and but it do a good job explain everything and keep it serious but entertain . i guess that you can always count on june foray ( most famously the voice of rocky the squirrel and she play a deer here ) . since hemo the magnificent itself may be hard to find and probably the best place to see it be in gremlin represent a class be watch it while a gremlin be form .
