What causes the lub-dup heart sounds that are heard with the stethoscope?
The cardiac sounds (typically described as lub-dub) are caused by the closing of the cardiac valves. The first sound (lub) is caused by the closing of the mitral and tricuspid valves and the second (dub) is caused by the closing of the aortic and pulmonic valves.
What causes the lub and dup of the heart?
The lub is caused by the closing of the AV valves. The dup is caused by the semilunar valves closing at the end of systole.
The heart valves are arranged with the?
valves in the heart are at the opening of the right and left auricle,poening of the right and left venticle and the closing of the right and left ventricle
What is normal heart sounds heard while the heart is working?
Valves opening and closing and blood flowingThe normal action of the heart, the pumping of the chambers and the closing of the valves.Closing of the valvesLub = closing the AV valvesDub = closing of the semi lunar valvesThe heart beats when the blood pumps
Is there any difference between the heart pumping blood and the heart beating?
Yes the "heart beat" is just the sound of the valves opening and closing, not the sound of the blood being pumped.

The normal heart sounds heard through a stethoscope are caused by the contractions of the ventricles?
Normal heart sounds (often called lub-dub) are caused by the pressure changes in the ventricles closing the various heart valves. The first sound, lub, is caused by the closing of the atrioventricular valves after the ventricles have filled with blood and as the ventricles begin to contract. The second sound, dub, is caused by the closing of the semilunar valves as the ventricles relax after pushing blood forward.
What action causes audible heart sounds?
The opening and closing of the heart valves.
Where does the sound of your heart pumping blood come from?
heart valves opening and closing
What causes the lub and dup of the heart?
The lub is caused by the closing of the AV valves. The dup is caused by the semilunar valves closing at the end of systole.
How is a heartbeat generated?
it is valves in the heart opening and closing.
What produce the heart sounds heard with a stethoscope?
The valves opening and closing
What cause the lubb-dupp heart sounds that are heard while talking an apical pulse?
The closing of the valves in the heart. The first sound is caused by the closing of the atrioventricular valves within the heart. The second sound is caused by the shutting of the aortic and pulmonary valves.
What does the beating sound of your heart come from?
The sound of a heart beat is caused by the closing of the valves in the heart.
The heart valves are arranged with the?
valves in the heart are at the opening of the right and left auricle,poening of the right and left venticle and the closing of the right and left ventricle

What are the source of beats in your heart?
The sources of the beats in your heart is the involuntary movement of the valves in your heart opening and closing between the atria and ventricles. The valves direct the blood to certain arteries as it enters through a vein. The valves open and close to make sure the correct blood (oxygen-rich or oxygen-poor) is going into the correct places. The opening and closing of the valves is instantaneous. Therefore, you have a heartbeat.
