What is the normal resting blood pressure of a healthy human adult measured in millimeters of mercury (mmHg)?
Answer and explanation
Correct answer: C. 120 / 80 mmHg
- Step 1: Systolic pressure corresponds to ventricular contraction; diastolic pressure corresponds to ventricular relaxation. Step 2. Standard adult resting arterial pressure is 120 mmHg systolic and 80 mmHg diastolic. Answer: 120 / 80 mmHg (systolic / diastolic). Why not the others: 140/90 is the clinical threshold for hypertension; 100/60 indicates hypotension; 80/120 reverses systolic and diastolic values.
