The period of time marked by contraction of the ventricles
It is called systole. This is when the ventricles contract and eject blood into the lungs (from the right ventricle) or into the systemic circulation (from left ventricle).
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.
Systole is the correct answer
Systole
Capillaries
d. contraction of the ventricles
Systole and diastole most often refer to the ventricle of the heart. Systole is contraction of the ventricle, and diastole is the relaxation of the ventricle.
contraction phase and relaxation phase of the ventricles
ventricular systole
systole
Contraction of the ventricles and atria is called systole. Relaxation is called diastole.

The cardiac cycle of the heart has two phases - the diastole phase and systole phase. In the systole phase, the ventricles contract and pump blood into the arteries.
Atrial systole -- The atrium contracts, then the ventricle.
Systole is the period of heart contraction within the cardiac cycle.
