DK Books is always a great place to start for learning books, and I've included one of theirs here. Plus, I found a couple of other books with illustrations that look really appealing. I've heard great reviews of the discontinued Your Human Body book too, which you can find used on Amazon. Beleduc's puzzle is a great beginners choice, and the Janod puzzle will grow with your kids - just highlight more details as they get older. I have a feeling I'll be learning right alongside my kiddo.
