What is the normal range for blood pressure in adults?

  1. 110/70 mmHg

  2. 120/80 mmHg

  3. 130/90 mmHg

  4. 140/90 mmHg

The correct answer is: 120/80 mmHg

The normal range for blood pressure in adults is defined as 120/80 mmHg. This measurement is widely accepted as the standard for what is considered optimal blood pressure. Blood pressure readings are expressed in millimeters of mercury (mmHg) and consist of two numbers: systolic pressure (the first number), which represents the pressure in the arteries when the heart beats, and diastolic pressure (the second number), which indicates the pressure in the arteries when the heart is at rest between beats. The value of 120/80 mmHg is associated with lower risks of heart-related conditions and is often referred to as 'normal' or 'ideal' blood pressure. It strikes a balance that is neither too low nor too high, making it beneficial for overall cardiovascular health. Readings above or below this range indicate different levels of blood pressure status, such as elevated, hypertension, or hypotension, which can have significant health implications. Thus, understanding the significance of the 120/80 mmHg standard helps in recognizing the state of a person's cardiovascular health.
