What is the normal blood pressure range?

• A. About 110-120/60-70 mmHg.
• B. 90-100/50-60 mmHg.
• C. 140-160/85-95 mmHg.
• D. 130-140/70-80 mmHg.

Answer: (A)

Normal blood pressure reflects the pressures in the arteries during heartbeats and in between beats. For healthy adults, the typical range is about 110-120 mmHg systolic and 60-70 mmHg diastolic. This combination represents a balance that supplies organs with enough blood flow without placing excessive strain on vessels. The value around 110-120/60-70 mmHg best matches what clinicians consider normal. Values significantly lower can cause dizziness or inadequate perfusion, while higher values indicate elevated blood pressure and increased cardiovascular risk. Ranges like 130-140/70-80 or 140-160/85-95 are not considered normal for routine health, though guidelines may vary on categorization of borderline or elevated pressures.
