Detailed explanation-1: -Systolic pressure is the maximum blood pressure during contraction of the ventricles; diastolic pressure is the minimum pressure recorded just prior to the next contraction. The blood pressure is usually written as the systolic pressure over the diastolic pressure (e.g., 120/80 mm Hg).
Detailed explanation-2: -The systolic pressure indicates the arterial pressure resulting from the ejection of blood during ventricular contraction, whereas the diastolic pressure represents the arterial pressure of blood during ventricular relaxation.
Detailed explanation-3: -Blood pressure represents the force (pressure) exerted by blood against the arterial walls during a cardiac cycle. <kt>Systolic pressure<kt>, the higher of the two blood pressure measurements, occurs during ventricular contraction (systole) as the heart propels 70 to 100 mL of blood into the aorta.
