In brief: Millisecond timing

The 2 atria act as reservoirs for returning blood; the 2 ventricles are the "pumpers".
The 4 chambers must be coordinated with millisecond timing to maximize the amount of blood pumped (cardiac output). This is done by a network of specialized cells which are found in tracts or bundles that conduct a micro-electrical current to time motion. A gross analogy: think of the distributor in your car.
