Do you know any ideas in making a 3D model of a Circulatory system?

   A small aquarium with plastic tubular air pumps and charcoal water filter is a pretty good model of a circulatory system.

   The aquarium water is like the blood and all the aquarium systems keep the blood moving, aerated and clean (free of other solid waste.)

   The tubular air pumps stand in the back corner of the aquarium. The air pumped into the bottom of the plastic tube rises, taking water with it. That keeps the water circulating (bottom to top) and aerates the water (kinda like lungs.)

   The more expensive systems will have a plastic grill over which aquarium rocks sit, and the tube will stand on the grill. This forces the water to be sucked through the rocks prior to rising through the tube — so rocks act as a filter for solid waste material prior to entering the tube for aeration. One could argue that this solid waste removal is analogous to the function of the liver and kidneys.

   The water filter uses siphons to suck water from the tank into the charcoal/cotton holding area, where solid wastes are trapped/removed. The clean water is pumped from the holding area back into the aquarium. This subsystem functions like the liver and kidneys.

   The fish in the aquarium are the beneficiaries of this circulatory system — they’re like the other parts of the body not directly involved in circulation of blood, but benefits by it.
