How does arteriosclerosis affect blood circulation?

It increases circulation
It restricts blood flow
It improves oxygen delivery
It enhances nutrient absorption

The correct answer is: It restricts blood flow

Arteriosclerosis is a condition characterized by the thickening and hardening of the arterial walls, typically due to plaque buildup. This alteration in the arteries leads to a reduction in their elasticity and narrowing of the lumen, which directly impacts blood flow. This restriction in blood flow can lead to several complications, such as hypertension and reduced oxygen and nutrient supply to tissues and organs. As the arteries become less flexible and more rigid, the heart must work harder to pump blood through these narrow passages, further exacerbating circulation difficulties. Therefore, the understanding that arteriosclerosis restricts blood flow is fundamentally important as it illustrates how this condition poses a risk for cardiovascular diseases and affects overall health.
