Solved: Arterial stenosis is a constriction of an artery, often due to plaque buildup on

Chapter 15, Problem 82

(choose chapter or problem)

Arterial stenosis is a constriction of an artery, often due to plaque buildup on the arterys inner walls. Serious medical conditions can result, depending on the affected artery. Stenosis of the carotid arteries that supply blood to the brain is a leading cause of stroke, while stenosis of the renal arteries can lead to kidney failure. Pulmonary artery stenosis results from birth defects, and can result in insufficient oxygen supply. Because the heart has to work harder to get blood through a constricted artery, stenosis can contribute to high blood pressure. In answering the questions below, assume steady flow (which is true in arteries only on short timescales). Which of the following medical problems is more likely to occur? a. An artery might collapse because of lower blood pressure at the stenosis. b. An artery might burst because of higher blood pressure at the stenosis. c. Neither; pressure at the stenosis is the same as in the surrounding artery.
