Blood pressure is the force exerted by blood against the vessel walls.During a normal cardiac cycle,blood pressure reaches a peak,followed by a trough,or low point,in the cycle.The peak pressure occurs when the heart's ventricular contraction,or systole,forces blood under high pressure into the aorta.The difference between systolic pressure and diastolic pressure is the pulse pressure.When the ventricles relax,the blood remaining in the arteries exerts a minimum or diastolic pressure.Diastolic pressure is the minimal pressure exerted against the arterial wall at all times.As the sphygmomanometer cuff is deflated,the five different sounds heard over an artery are called Korotkoff phases.
