Systolic and Diastolic Blood Pressure
When ventricles (the part of the heart that pumps blood) 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.
