Explanation

Blood pressure is the pressure exerted by circulating blood upon the walls of blood vessels. It is measured in millimeters of mercury (mmHg). During each heartbeat, the blood pressure varies between a maximum (systolic) and a minimum (diastolic) pressure. A healthy person has a blood pressure below 120 over 80 (120/80).
