Question

The difference between systolic and diastolic pressure in humans is:

• A. 40 mm Hg
• B. 80 mm Hg
• C. 120 mm Hg
• D. 200 mm Hg

Answer 1

The correct option is A

40 mm Hg

The top number is the maximum pressure your heart exerts while beating (systolic pressure), and the bottom number is the amount of pressure in your arteries between beats (diastolic pressure). The numeric difference between your systolic and diastolic blood pressure is called your pulse pressure.
