What is the name of the condition where blood vessels become narrowed or blocked?

• A. stenosis
• B. atherosclerosis
• C. hemorrhage
• D. bruit

Answer: (B)

The condition where blood vessels become narrowed or blocked is known as atherosclerosis. This is a progressive disease characterized by the buildup of fatty deposits, cholesterol, and other substances on the inner walls of arteries, forming plaques. As the plaques accumulate, they can cause the arteries to harden and narrow, leading to a reduction in blood flow. This process can significantly impact circulation and may result in serious cardiovascular problems such as heart attacks or strokes.

The other terms relate to different vascular issues or physiological phenomena. Stenosis refers more broadly to any narrowing of a bodily passage, including but not limited to blood vessels, which doesn't capture the specific nature of atherosclerosis. Hemorrhage refers to bleeding, while bruit is a sound heard over an artery that indicates turbulence in blood flow and is often associated with conditions such as stenosis or occlusion but does not describe the underlying process like atherosclerosis does. Thus, atherosclerosis is the correct term for the condition described.
