We watched a movie called "The Incredible Human Machine".  One of the most amazing things was the camera that was placed in a rock stars throat so that you could see his vocal chords.  His blood vessels were coming out (broken) and so the doctor used a laser to cauterize them.  All the parts of the body made more sense seeing them up close like that.  We also got a cool CD that has songs and videos about science.  Here is one of my favorites: 

The Bloodmobile

The Bloodmobile The Bloodmobile A delivery service inside us We begin in the heart's right ventricle And travel to the lungs Red blood cells get oxygen To take back to the heart Then from the left side of the heart And out to every cell Delivered by the Bloodmobile The food that's been digested Is waiting at the dock To be taken to the tissues In the body's grocery truck So from the small intestine It's carried everywhere Delivered by the Bloodmobile The Bloodmobile The Bloodmobile A delivery service inside us The white blood cells are soldiers That fight infectious germs They make the antibodies Their weapons in the fight The army is transported Wherever they must go Delivered by the Bloodmobile We need to send a message To tell a limb to grow Or speed the heart or regulate Your hunger or your sleep The hormones are the message They're sent from many glands The messenger's the Bloodmobile [Spoken:] Somebody's got to haul out the trash To the liver and the kidneys It's not a pretty job Carbon dioxide gets carried To the lungs to be exhaled And the garbage truck is the Bloodmobile The Bloodmobile The Bloodmobile A delivery service inside us To carry oxygen, nutrients, things that fight infections Do the trash collection and deliver the mail And we're all (and we're all) Delivered by the Bloodmobile
