What heart sound is stronger at the apex of the heart?
First heart sound S1-LUB
What are the heart chambers that are filled when you hear the first heart sound?
after the first heart sound is made ventricles starts emptying.
The first heart sound lub is caused by what?
The "lubb" sound is produced when the atrioventricular valves in the heart close.
Where is the s1 heart sound heard the loudest?
S1 makes a "lub" sound. It is the first heart sound in a normal rhythm. The sound is produced when the AV valves close.
When your heart pounds what is making the sound come from your heart?
The sound coming from your heart is the sound of the valves in the heart closing and the turbulence in the blood that results. In a normal healthy adult the first sound (or lub) is from the closing of the AV valve and the second sound (or dub) is from the closing of the semilunar valve.
The heart chambers that have just been filled when you hear the first heart sound are the?
atria
What parts of the heart make the beating sound?
The first heart sound, the so called "lub", comes from the closure of the atrioventricular valve. The second heart sound, the "dup", comes from the closure of the semilunar valve.
What are the clumbers that have been emptied after the first heart sound?
Atriums
Would turbulence of blood flow through the aortic valve give rise to the first heart sound?
No. The heart sounds are caused by the closure of heart valves. The first heart sound is caused by the closure of the AV valves (tricuspid and mitral). The second heart sound is the result of the closure of the aortic and pulmonic valve after the completion of systole. Turbulence of blood flow through the aortic valve would cause a murmur (an abnormal heart sound) during systole.
What does a healthy heart sound?
In healthy adults, there are two normal heart sounds often described as a lub and a dub, that occur in sequence with each heart beat. These are the first heart sound (S1) and second heart sound (S2), produced by the closing of the AV valves and semilunar valves respectively.
The first heart sound is heard when?
S1 which is the closing of the atrioventricular valves.
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.
