What is the expected normal range for adult blood pressure?

The expected normal range for adult blood pressure is commonly established as between 90/60 mmHg to 120/80 mmHg. This range reflects typical physiological values for adults at rest and indicates optimal blood flow and pressure within the cardiovascular system.

Blood pressure is recorded with two numbers: the systolic pressure, which measures the pressure in the arteries when the heart beats, and the diastolic pressure, which measures the pressure in the arteries when the heart rests between beats. The normal range signifies that both systolic and diastolic pressures are within a healthy limit, promoting effective circulation and reducing the risk of cardiovascular diseases.

The values stated in the other choices fall outside the commonly accepted normal range for adults. For instance, the first choice suggests a range that is too low and could indicate hypotension, while the ranges provided in the other options could imply borderline or elevated blood pressure, which may necessitate monitoring or further evaluation.

Understanding these ranges is crucial for identifying and managing blood pressure health, making the choice indicating 90/60 mmHg to 120/80 mmHg the most accurate representation of normal adult blood pressure.
