What is the normal range for adult blood pressure?

The correct choice identifies the normal blood pressure range for adults as 90/60 mmHg to 120/80 mmHg. Blood pressure is classified as normal when it records a systolic value (the first number) below 120 mmHg and a diastolic value (the second number) below 80 mmHg. This range indicates that the cardiovascular system is functioning effectively without excessive strain.

Maintaining blood pressure within these limits is important for overall health, as deviations can signify various health issues. Readings consistently above these figures may indicate prehypertension or hypertension, which can lead to serious health complications over time, including heart disease and stroke. Conversely, very low measurements may suggest hypotension, which can also pose health risks.

By providing a widely accepted reference point for blood pressure, this choice helps underline the importance of regular monitoring and the possible implications of abnormal readings.
