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.
When your heart goes bump bump is that one or to heart beats?
It really is lubb dupp and it is the sound of the 4 valves closing, two at a time. This occurs during one heart beat.
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.
How is a heart beat produced?
The heart beat, also called heart sounds, is produced by the closing of the valves. The valves produce two sounds, known as lub-dub. The atrioventricular valve closing produces the first sound, or lub, and the semilunar valve closing produces the second sound, or dub.
The beating sound your heart makes comes from?
From the closure of the two flaps of the mitral valve in the left ventricle
What are sound conclusions?
sound is a mechanical wave.Sound can be of two types :music and noise. sound gets reflected. we need about 300 metres for a good echo to be heard. there are audible and inaudible sounds. audible from 20Hz to 20000Hz.below 20Hz and above 20000Hz are inaudible sounds.There are infrasonic and ultrasonic sounds.

Use audible in a sentence?
The music was so loud, it was audible two stories up.
How are blood vessels important for the functioning of the heart?
Blood vessels help transport blood to and from the heart. Without them, one, you would be dead, and two, your heart would be useless and would do nothing.
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.
Any sound wave with frequencies higher than 20000 hz?
The sound which is over 20 000 Hz is called ultrasonic. It can't be heard by human ears. It can be heard and produce by some of the animals and mammals e.g.-Dolphin,bat etc. The sound which is less then 20 Hz is called infrasonic. The sound is divided into these two parts.

How many receiving chambers and outgoing chambers does the human heart have?
The human heart has two receiving and two outgoing chambers. Without the proper functioning of all chambers, the heart may have problems.
Why does your heart do two beats ie badum not ba?
One sound is the atrial beat, the other the ventricular one.
The second heart sound is caused by?
Closure of the two atrioventricular valves, specifically the tricuspid and mitral valves.
