They work together by being in the heart
When relaxed, the atria expand, and then the ventricles contract.
Yes, atria contracts before the ventricles.
Its a Dual Pump because it contains 2 pumps, the atria and the ventricles. Atria work as a weak primer pump that pump to the ventricles and ventricles are the major pump that distributes it.
the difference between the ventricles and the atria is that the ventricles are thicker
Atria don't do nearly the same amount of work of contraction as do the ventricles. They are therefore relatively thin walled. Most of the blood that flows from the atria to the ventricles flows passively, and so the atria function mostly as a reservoir for blood volume.

ventricles
The Atria and Ventricles are parts of the heart not the blood. The Atria is the upper chambers of the heart and the Ventricles are the lower chambers of the heart.
There are no valves between the atria. The valves between the atria and ventricles close when the ventricles contract.
atria are just the receiving chambers, it is the ventricles that actually pump the blood into the pulmonary and systemic circuits
I believe this would be your heart because that is the only time ventricles and atria are brought up.
The atrioventricular valves are two heart valves that allow for the transportation of blood from the atria to the ventricles of the heart. Its function is to prevent the return of blood to the atrium.
