Quizplus · Accepted Answer

When heart valves do not close properly, a turbulence is created within the heart, which leads to a heart murmur. A stethoscope can detect the sound of the murmur as an abnormal swishing or whooshing noise. Therefore, the correct choice is C. Atherosclerosis refers to the buildup of plaque in the arteries, and it is not related to the closing of heart valves. A major heart defect may or may not result in a heart murmur, so D is not a specific answer. Similarly, A (lub dub) is the normal sound heard when the heart valves close properly, and it does not indicate a problem with the valve closure.
