What is considered a normal blood pressure reading?

A normal blood pressure reading is generally defined as one that falls within the range recognized by health organizations. The American Heart Association classifies normal blood pressure as being below 120/80 mmHg. In this context, a reading of 120/70 mmHg is well within the normal range, making it ideal for maintaining cardiovascular health.

Blood pressure readings are expressed in millimeters of mercury (mmHg) and consist of two numbers: systolic pressure (the first, higher number) represents the pressure in the arteries when the heart beats, while diastolic pressure (the second, lower number) indicates the pressure when the heart is at rest between beats. A systolic reading of 120 is considered the upper limit of normal, and a diastolic reading of 70 remains within the normal range, confirming that this specific reading is a standard representation of healthy blood pressure.

Other options, while they may still fall within acceptable limits, reflect varying levels of hypertension or at least increased risk. Thus, while B is the most representative of what is classified as normal blood pressure, others indicate that further monitoring or lifestyle adjustments might be advisable.
