What's sound of the heart?
Most people can hear two heart sounds per cycle - a quiet "lub" and a louder "dub". The "lub" sound is the contraction of the two atria, which results in the ventricles being filled with blood. The "dub" sound is the contraction of the two ventricles, which results in blood being forced into the arterial system. However, a trained physician can hear four sounds - the two described above, and two more that represent the sound of the valves opening back up after the contraction is over.
Which part of the heart makes the heartbeat sound?
A heartbeat produces the familiar "LUB-DUP" sounds as the chambers contract and the valves close. The first heart sound, "lub," is heard when the ventricles contract and the atrioventricular valves close. This sound last longest and has a lower pitch. The second heart sound, "dub," is heard when the relaxation of the ventricles allows the semilunar valves to close.
What is an endocardiogram?
This is a procedure that checks the status of the heart chambers and valves. Sound waves are used to produce images of the heart and check for any problem in heart muscles or valves. This exam is usually suggested if a doctor believes that the patients blood is being pumped abnormally.
The heart sounds are due to?
The sounds in the heart are caused by the opening and closing of the ventricles. There are two sounds and they are called by the first heart sound (S1) and second heart sound (S2), produced by the closing of the AtrioVentricular valves and semilunar valves respectively.
What is lubb-dubb sound when listening to the heart?
It's the sound of the blood hitting the walls of the valves as they close. That is pretty much the most basic way to explain it.The first heart sound a low pitched "lubb it is caused by vibration of the AV valves and surrounding fluid as the valves close at the begining of ventricular systole and the 2nd heart sound "dub" results from the closure of the aortic and pulmonary semilunar valves at the begining of ventricle diastole.The lub-dub sound is caused by the opening and closing of valves in the heart.The lub sound is caused by the shutting of the bicuspid/mitral valve and the tricuspid valve. This occurs when blood from the atrial chambers enter the ventricles.The dub sound is caused by the shutting of the aortic valve and the pulmonary valve. This occurs when the blood from the ventricles are pumped out into the lungs and the rest of the body.This cycle will then repeat itself hence the constant lub-dub lub-dub lub-dub etcThe answer to that question is actually quite simple. I don't know if what you are asking is why does it make a thumping sound?? But if that is the case then I can answer that question. The sound you hear is the heart producing blood and circulating it throughout the body.Hope that helps....The 'lub' is the S1 sound. It occurs due to normal closure of the mitral and tricuspid (atrioventricular) valves. With these valves closed, systole commences and blood is actively squeezed from the ventricles. The second sound is the 'dub' or S2 sound. It occurs as the aortic (to LV) and pulmonary (to RV) valves close to prevent backflow from the blood ejected from the ventricles and marks the beginning of diastole (or filling) of the heart.The "lubb" sound is produced when the atrioventricular valves in the heart close. These valves are deep inside the heart and are between the upper (atrial) and lower (ventricular) chambers. The "dupp" sound is created when the semilunar valves (aortic and pulmonary) close.These valves are at the top of the heart and lead to the arteries that carry blood to either the lungs or the body. The "lubb" is the first heart sound and softer. The "dupp" sound is shorter and louder than the "lubb" sound. This is because the cusps of the semilunar valves are more rigid than the atrioventricular valves (mitral and tricuspid).The closing of the heart valves.Blood pumping through.
The heart chambers that have just been filled when you hear the first heart sound are the?
atria
What causes the sounds that are normally heard when listening to the heart through a stethoscope?
The sound is caused by the closing of valves in the heart.
When you hear the first heart sound the chambers that have just emptied are the?
I believe it's the right and left atria.
What makes the first sound of a heartbeat?
The first sound, LUB, is made after the ventricular systole due to the shutting of bicuspid and tricuspid (AV) valves.
What is filled with blood after the second heart sound?
right atrium

What is filling after the second heart sound?
The heart makes a "lub-dub" sound. The first is when the AV valves close and the ventricles are filled. The second is when the semi-lunar vlaves close and the blood is sent to the lungs, or to the rest of the body.

What heart sound is stronger at the apex of the heart?
First heart sound S1-LUB
What is the Lub-Dub sound?
In the lub-dub version of heart sound, dub is caused by the back rush of blood against a closed aortic or pulmonary valve.

The first heart sound lub is caused by what?
The "lubb" sound is produced when the atrioventricular valves in the heart close.
