Summary Introduction
Introduction: The pressure exerted by the circulating blood against the blood vessel wall is called blood pressure. The heart contractions generate the blood pressure. The blood pressure is measured in millimeters of mercury (mmHg). The blood pressure is normally expressed as systolic pressure over diastolic pressure.
