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
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 prevents blood from flowing back into the heart?
The valve
When the Blood leaves the left atrium through what valve?
This valve has different names. It is the LAV valve or Mitral Valve or Bicuspid valve.
Where does blood flow after the right AV valve?
After the right AV valve, the blood flows into the right ventricle.
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
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 valve sound heard at base of the heart?
The valve sound heard at the base of the heart is primarily the aortic valve closure. This sound is best heard using the diaphragm of the stethoscope at the second right intercostal space along the sternal border. It represents the closing of the aortic valve as blood is ejected from the left ventricle into the aorta during systole.
The sound created when blood leaks back through an incompletely closed valve is called what?
The sound created when blood leaks back through an incompletely closed valve is called a heart murmur. This can occur due to various conditions affecting the heart valves.
What is the function of semi-lunar aortic valve?
It prevents blood flowing back into the heart from the arteries.
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 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.
How is a mitral valve insufficiency first detected?
When the doctor listens to the heart sounds, mitral valve insufficiency is generally recognized by the sound the blood makes as it leaks backward. It sounds like a regurgitant murmur.
Mitral valve prolapse is a disorder of the heart in which the mitral valve?
The valve becomes thickened and doesn't work correctly. I have heard it called floppy valve. It doesn't close tightly as it should and it can be "leaky". Some blood flows backwards. This can be heard as a "murmur". It also can be seen on an ultra-sound.
Where does the pushing force come from to push the blood out the heart?
The heart has two pumps inside of it and each has two chambers and two valves. The left side of the heart has the biggest chambers, and the one that pumps the blood to your body is called the left ventricle, When it contracts (squeezes together), the first valve closes shut (that's the "lupp" sound of a heart beat) and the contraction pushes the blood up past the second valve and into aorta, which is the main artery that distributes the blood to the regular arteries that carry the blood throughout the body. When the blood goes into the aorta, the second valve shuts so the blood doesn't go backwards into the heart and that is the "dubb" sound of a heart beat.
What prevents blood from flowing back into the heart?
The valve
What if the name of the valve on the vessel that takes blood from the heart?
The valve on the aorta (the vessel taking blood away from the heart) is called the "aortic valve".
