Question

sabrina you refer to the cardiac cycle, and the heart sounds in your post. how do heart sounds relate to blood flow in the heart? anatomical and functional changes in the heart can lead to changing heart rhythm and heart sounds. take a look at the website about heart murmurs and rhythms. easy auscultation has great lessons to learn normal heart sounds, and relate auscultation to cardiac cycles.

Explanation:

Heart sounds are produced by the closing of heart valves during the cardiac - cycle. Normal heart sounds (S1 and S2) occur as the atrioventricular and semilunar valves close respectively, which is related to the direction and pressure of blood - flow in the heart. Abnormal heart sounds like murmurs can indicate problems such as valve stenosis or regurgitation, which disrupt normal blood - flow patterns. Auscultation is the method of listening to these sounds to assess heart function.

Answer:

Heart sounds are produced by valve - closure events during the cardiac cycle and are related to the normal and abnormal patterns of blood - flow in the heart. Auscultation is used to listen to these sounds for assessment.
