C has become really, really interested in her body and the human body in general since she got a very simple book about the human body from Mimi while we were on vacation. This book was definitely her age level, maybe a bit above, but she loves to read it, look at the pictures, tell us about what it says, ask the same questions over and over…which of course I love, being fascinated with the human body myself. Hearing your four year old explain that you make 3 cups of saliva per day and that one side of your brain helps with things like counting and one side of your brain helps with things like coloring is just, well, kinda funny. She asks what things are, I tell her. Why not? We’ve moved from ‘arm bone’ to humerus, radius and ulna. She asked what that space was on the inside of your elbow [a common site for having your blood drawn]…I explained that the back part of your arm there is called the elbow; “but what’s this part called?” she asked. So I told her, that’s the antecubital fossa. “What’s the antecubital fossa?,” she wondered out loud…
But we’d conquered the vacation body book, so at the library on Saturday, we scouted out some new ones. The one she picked was quite thick, probably aimed at an older school-age child. Lots more drawings and pictures and figures, some electron microscopy photographs (”Oooooooh, what’s that?!?”, she says, on seeing electron microscopy of a macrophage engulfing a germ. She totally understood my explanation of phagocytosis, but not so much electron microscopy), x-rays, all that fun stuff. When we got to the pages devoted to the heart, there was one picture showing a cross section of the heart, similar to this:

She was intrigued by the valves. “What’s this called?,” she asked. I explained that they were valves. “What’s a valve?,” she inquired. So I showed with my hands, it’s something that opens and closes. She recalled a toy she had gotten at Family Fun Night about 3 months ago, one of those clapper things on a handle that is exceptionally loud and annoying, but also happens to be strangely enough like a valve that she knew exactly what I was describing.
“Who pulls those strings?,” she wondered. “What strings?,” I said. “Those strings there, those white strings, who pulls those strings on the valves?” I said they sort of operate on their own, no one needs to pull them, they just pull the valves open and shut on their own. She said, “Well I mean you can have Jesus in your heart but where are the people who will pull those strings, is there room for those people if you have Jesus in your heart?”
