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.
The two phases of the Cell Cycle are:InterphaseMitosis
The two main phases of cell cycles are the interphase and the mitotic phase.
Respiration occurs in two phases: anaerobic, which does not require oxygen, and aerobic which does require oxygen.
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.
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.
The two phases of the heartbeat are systole (contraction phase) and diastole (relaxation phase).
The human heartbeat has two phases. The systolic phase corresponds with contraction, and the diastolic phase with relaxation.
Diastole (relaxation) Systole (contraction)

contraction and expansion.
the pumping and the not pumping? diastollic and systollic?
The two main phases of a persons sleep, is REM sleep, Rapid Eye Movement, which is when you dream, and just a normal deep sleep. This happens every 90 minutes.

Law with Two Phases was created in 1984.
