The Cardiovascular Construction Kit (CVCK) allows you, the user, to design and construct a wide range of cardiovascular systems, testing each one to see how it behaves - and whether it could actually exist and survive in a real organism. The Kit provides you with a set of basic components, e.g., pumps, vessels, capillaries and so on, which you may piece together to construct to build a cardiovascular system you are interested in exploring. Gauges and measurement techniques are provided so you can draw conclusions from your experiments.
