What are systolic pressure and diastolic blood pressure?
When ventricles contract and pump blood out of the
heart, the blood pressure reaches its maximum value in
the cycle, which is called systolic pressure.
When the ventricles relax, the blood pressure reaches
its minimum value in the cycle, which is called diastolic
pressure.
