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.
What valve causes the second heart sound?
The closing of the mitral and tricuspid valves results in the first heart sound. The closing of the aortic and pulmonic valves results in the second heart sound.AV valve
Which heart sound results from the AV valves closing?
S2, also called the second heart sound, or "dub" when characterized by the sound lub-dub.
What is the sound of second heart sound?
The second heart sound (S2) is a short burst of auditory vibrations of varying intensity, frequency, quality, and duration. It has two audible components, the aortic closure sound (A2) and the pulmonic closure sound (P2), which are normally split on inspiration and virtually single on expiration. S2 is produced in part by hemodynamic events immediately following closure of the aortic and pulmonic valves. The vibrations of the second heart sound occur at the end of ventricular contraction and identify the onset of ventricular diastole and the end of mechanical systole.
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 is filled with blood after the second heart sound?
right atrium
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.
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.
The second heart sound occurs as a result of valve closure due to?
The second heart sound, also called S2, is a result of the closing of the aortic and pulmonic valves. The heart sounds are described as sounding like "lub-dub".
What produces the systolic korotkoff sound?
The first Korotkoff sound is the sound produced by the turbulence of the AV (atrioventricular valves) closing specifically the tricuspid and mitral valves. The second Korotkoff sound is produced by the closure of the aortic and pulmonary valves. You can hear a splitting of the second heart sound in a highly efficient heart.
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.
How does venous pressure rise during 2nd heart sound?
The venous pressure increases during the second heart sound because of the increased negative pressure. 2nd heart sound heard when AV valves close,ventricular diastole
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.
Which valves produce the second heart sound when they snap shut?
Isovolumetric relaxation: In this phase the ventricles relax, the intraventricular pressure decreases. When this occurs, a pressure gradient reversal causes the aortic and pulmonary valves to abruptly close (aortic before pulmonary), causing the second heart sound.
