Students manipulate the inner workings of the human body as they build the models, gaining a deeper understanding of how organs and systems interact. Perfect for human body centers focusing on major organs or the circulatory, nervous or skeletal systems. Each realistically detailed plastic model includes a display stand and guide with facts and step by step, photo-illustrated assembly instructions.
