In a normal adult human the difference between the systolic and diastolic pressure is
- A. 40 mm Hg
- B. 20 mm Hg
- C. 80 mm Hg
- D. 120 mm Hg
Answer: A. 40 mm Hg
The difference between systolic and diastolic pressure is called as pulse pressure. It is measured in millimeters of mercury.
- Systolic pressure is the maximum pressure exerted by the heart when it contracts, and in a healthy adult, it usually ranges from 120 mm Hg.
- Diastolic pressure is the pressure in the arteries between heartbeats, and it typically falls between 80 mm Hg.
- So the pulse pressure will be 40 mm Hg.
