Detailed explanation-1: -Systolic blood pressure is measured when the heart ventricles contract. Diastolic blood pressure is measured when the heart ventricles relax. A systolic pressure of 115 millimeters of mercury is considered normal, as is a diastolic pressure of 70. Commonly, this pressure would be stated as 115 over 70.
Detailed explanation-2: -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.
Detailed explanation-3: -The pressure of blood inside the arteries during ventricular contraction is called systolic pressure and the pressure in the arteries during ventricular relaxation is called diastolic pressure.
