What are systolic pressure and diastolic pressure?
When ventricles contract and pump blood out of the heart, blood pressure reaches its maximum value, the highest pressure in the cycle is
known as systolic pressure. When the heart relaxes between heartbeats, the lowest blood pressure is diastolic pressure.
