B
The difference between systolic and diastolic pressure is the pulse pressure. For a blood pressure (BP) of 120/80 mm Hg, the pulse pressure is 40 . When the ventricles relax, the blood remaining in the arteries exerts a minimum or diastolic pressure. Under high pressure, the left ventricle ejects blood into the aorta; the peak pressure is known as systolic pressure. The most common alteration in blood pressure is hypertension, an often asymptomatic disorder characterized by persistently elevated BP. Hypertension is defined as systolic blood pressure (SBP) greater than 140 mm Hg, diastolic blood pressure (DBP) greater than 90 mm Hg.
