The blood pressure reading 120/80 mmHg represents the systolic pressure (120 mmHg) over the diastolic pressure (80 mmHg). Systolic pressure is the peak pressure in the arteries during ventricular contraction (systole), while diastolic pressure is the lowest pressure in the arteries during ventricular relaxation (diastole). Therefore, 120 mmHg represents the pressure during ventricular contraction and 80 mmHg represents the pressure during ventricular relaxation.
Systolic pressure corresponds to ventricular contraction; diastolic pressure corresponds to ventricular relaxation.
