1. Why is atherosclerosis dangerous to arterial function?
- A. It diminishes central circulation
- B. It causes decreased blood pressure on artery walls
- C. It narrows the arterial lumen so a clot can easily block it
- D. It increases arterial elasticity
Correct answer: C
Rationale: Atherosclerosis is dangerous to arterial function because it narrows the arterial lumen, increasing the risk of a clot completely blocking the blood flow. This can lead to severe cardiovascular events such as heart attacks or strokes. Choice A is incorrect since atherosclerosis does not primarily diminish central circulation, but rather, it impedes local blood flow where the plaque is present. Choice B is also incorrect as atherosclerosis increases the pressure on artery walls due to the narrowed space for blood flow, not decrease it. Lastly, choice D is incorrect as atherosclerosis causes the arteries to lose their elasticity, not increase it.
