Blood pressure is the measurement of the pressure or force of blood inside your arteries. Each time your heart beats, it pumps blood into arteries that carry blood throughout your body. This happens 60 to 100 times a minute, 24 hours a day. Arteries deliver oxygen and nutrients to your whole body so it can function. An increase in heart rate doesn’t mean your blood pressure is going up, too. The only way to know your blood pressure is to measure it with a blood pressure cuff and gauge. | Clevela
