There is the contraction of the atria and the contraction of the ventricles. When the atria contract, the AV valves are open, allowing the blood to fall into the ventricles. The AV valves then close, and the ventricles contract, pumping the blood out into the arteries.

Respiration occurs in two phases: anaerobic, which does not require oxygen, and aerobic which does require oxygen.
What are the two main phases of cell division in order?
The two main phases of cell division are mitosis and cytokinesis. Mitosis involves the division of the cell's nucleus into two identical daughter nuclei, while cytokinesis is the physical splitting of the cell into two separate daughter cells.
When are two phases at equilibrium?
Two phases are at equilibrium when the rate of their interconversion is equal in both directions. This means that the amount of substance transitioning from one phase to another is the same in both directions, resulting in a stable balance between the phases.

What is the period of time called between the beginning of one heartbeat and the start of the next?
The period of time between the beginning of one heartbeat and the start of the next is known as the cardiac cycle. It consists of two phases: systole (contraction of the heart muscles) and diastole (relaxation of the heart muscles).
