How can I construct a working 3d model of the circulatory system?

I need to make a working 3d model of the circulatory system....... any suggestions about how i could do it using easy to find materials? If you are blank about circulatory, can you give me suggestions on how to make other systems?

1. Ok, what you need is a straw , tube, water, red food dye, and a pumper.You put a hole in the tube, then put the straw there. Put red food dye in the water, and mix it around for a few secounds.Then pour the red water into the straw, and use the pupmer to pum it around in a circle. This is called a Closed Circulatory system. For open circ. Tube(Short), Pumper,Red Dye, Water,Plate(Or bowl). Place the pumper at one end of the tube, then the food dye in the other side. Pump the water into the bowl or plate then squzze it back in. Digestion is also there, so i think i should tell you. Brown clay, an old sock, Bannana, grape, macoroni, a spatula, knife, and a spoon. You cut up the food like your teeth would, then mix it up with a spoon, then you shove it doun the sock, make sure you put a hole at the end of the sock.Put the clay like dung, at the end of the sock, and when you shove the food down, use the spatula to much it. Then you keep pushing it down, then you stop pushing the food, and start pushing the clay. The clay represents the un needed stuff that we need to dispose. Hope i Helped you.
