What is blood pressure?

Blood pressure 1

Blood pressure is a measurement expressed in millimeters of mercury (mmHg) of the force that moves blood through our circulatory system. Blood pressure is recorded as two numbers, the systolic pressure and diastolic pressure.

Systolic pressure is the measurement of the pressure as the heat beats. Diastolic pressure is the measurement of the pressure as the heart relaxes between beats.

These measurement are written one before or above the other, with the systolic number before or on top and the diastolic number after or on the bottom.
