What is the normal range for adult human blood pressure?

The standard reference for normal blood pressure in adults is 120/80 mmHg. This measurement reflects the pressure in the arteries when the heart beats (systolic pressure, the first number) and the pressure in the arteries when the heart rests between beats (diastolic pressure, the second number). Blood pressure is categorized based on these measurements, and 120/80 mmHg is widely recognized as the benchmark for what is considered normal.

This range indicates that the heart is effectively pumping blood without exerting excessive pressure on the arterial walls, which helps in maintaining overall cardiovascular health. Values significantly above or below this range may be indicative of potential health issues, such as hypertension or hypotension, warranting further evaluation and management.

While other options present values that are relatively close, they do not represent the established guidelines for normal blood pressure, thereby distinguishing 120/80 mmHg as the optimal reference point in adult health assessments.
