A crayfish has one heart that contains two chambers
A crayfish has an open circulatory system while humans have a closed circulatory system. "Closed" means that we have true blood vessels that carry blood to and from the heart. "Open" means that the organs are simply bathed in blood that freely circulates around the body. Sometimes the heart can move the "blood" by creating pressure waves in the fluid.

Food, and that is pretty much it.
The heart of the crayfish pumps to circulate the blood. The blood flows through the open cavities as there is a minimum of tubing in the crayfish. The circulation of the blood aerates and purifies it.
