Needing Kindergarten Lessons About Bones, Blood, and Brain.

Our curriculum required I teach about the human body; but I only had six weeks to do it in.  Because it would be impossible to teach everything about the body in that time, I let the students tell me what they were most interested in.  It boiled down to brain, bloods, and bones.  The problem is, these systems are not really taught in most Kindergarten science books.  I would love some advice on how to teach these systems to Kindergarteners in an inquiry-based and engaging way.  Thanks.
