We are creating a cart and demonstration on the heart, and would like to
include the sound of  heartbeats from hearts with different numbers of
chambers and sizes.  We're having a hard time running them down.  Any leads
would be much appreciated:

*	2 chambered heart (shark)
*	3 chambered heart (snake or frog)
*	4 chambered hearts (giraffe, hummingbird or a variety of bird sizes,
healthy human, diseased human, infant human)

Thanks!
