Blood pressure is the force of blood pushing against the walls of your arteries as your heart pumps blood throughout your body. It is measured in millimeters of mercury (mmHg) and is expressed as two numbers: systolic pressure and diastolic pressure. The systolic pressure is the higher number and represents the pressure in your arteries when your heart beats, while the diastolic pressure is the lower number and represents the pressure in your arteries when your heart is resting between beats.
