Pseudo-discrete question from Kaplan's Fluid & Solid Topical Test:
Why is diastolic blood pressure murch lower than systolic blood pressure ? (Note: A typical systole/diastole reading is mmHg is 120/80)
A. Because the heart exerts more force on the blood during diastole.
B. Because the heart exerts no force on the blood during diastole.
C. Because the radii of the blood vessels increase during diastole, while the force exerted by the heart on the blood remains the same.
D. Because the radii of the blood vessels decrease during diastole, while the force exerted by the heart on the blood remains the same.
The answer is hidden in white, highlight: B.
Q: So, is the pressure in diastole then entirely due to constriction of the arterioles and arteries?
About Choice C...is the part about radii true? What happens to the radii of blood vessels during diastole?
