Normal blood pressure measured in millimeters of mercury is:

by

(A) 100/90 mmHg
(B) 120/80 mmHg
(C) 120/60 mmHg
(D) 90/70 mmHg

🧠 Explanation:

  • Blood pressure is measured in millimeters of mercury (mmHg) and consists of two values: systolic and diastolic.
  • 120 mmHg represents the systolic pressure (when the heart beats), and 80 mmHg is the diastolic pressure (when the heart rests between beats).
  • This reading — 120/80 mmHg — is considered the standard or normal blood pressure for a healthy adult.
  • Therefore, the correct answer is (B) 120/80 mmHg.
