What is the term for abnormal heart sounds caused by valvular abnormalities?
Murmurs
What is the term for the condition where a valve doesn't open widely enough, causing turbulent flow and a murmur?
Stenosis
What is the term for the condition where a valve doesn't close tightly, causing backflow of blood and a murmur?

What causes a noisy turbulent flow and a murmur in the case of valve regurgitation?
Backflow
What would happen if the mitral valve didn't close fully after the left ventricle relaxed?
All of the above
When can heart murmurs be heard?
During both systole and diastole
What can cause a valve to not close fully or not open widely enough?
All of the above
