Blood Pressure
 
 
Blood pressure is a measurement of the force applied to the walls of the arteries as the heart pumps blood through your body. The pressure is determined by the force and amount of blood pumped, and the size and flexibility of the arteries.

Blood pressure is continually changing depending on activity, temperature, diet, emotional state, posture, physical state, and medication use.

During each heartbeat, blood pressure varies between a maximum (systolic) and a minimum (diastolic) pressure.

The measurement blood pressure without further specification usually refers to the systemic arterial pressure measured at a person's upper arm and is a measure of the pressure in the brachial artery, major artery in the upper arm. A person's blood pressure is usually expressed in terms of the systolic pressure over diastolic pressure and is measured in millimetres of mercury (mmHg), for example 140/90.
