Why the first and second heart sounds different in intensity or pitch?
One is the heart pumping blood out, into the body. The second is the heart's intake beat; moving more blood into itself for the next pump. The intake is at less pressure than the pump out, so it is less strain on the muscle and sounds lighter.
The lub or first heart sound is produced by the closing of?
there are 2 sounds the heart makes. "lub-dub" the first ("lub") is when the atrioventricular valves sclose the second ("dub") is when the semilunar valves close
What is the origin of heart sounds?
Heart sounds originate from the closure of heart valves during the cardiac cycle. The first heart sound (S1) is produced by the closure of the mitral and tricuspid valves, while the second heart sound (S2) is caused by the closure of the aortic and pulmonary valves. These sounds can be heard using a stethoscope during a physical examination.
What causes the lub-dup heart sounds that are heard with the stethoscope?
The cardiac sounds (typically described as lub-dub) are caused by the closing of the cardiac valves. The first sound (lub) is caused by the closing of the mitral and tricuspid valves and the second (dub) is caused by the closing of the aortic and pulmonic valves.
How many sounds do you listen for when listening for an Apical heart beat?
two: first S1 lub for the AV and second Dub for the semilunar valves.
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.
What sounds does a 'healthy heart' make?
slow
The monosyllables describing heart sounds during the cardiac cycle is the?
HCA? I believe it's "lub" and "dup". (p. 493, under "heart sounds" heading...second sentence)
What events in the cardiac cycle cause the first and second heart sounds?
The closing of the mitral and tricuspid valves create the "lubb" and the closing of the semilunar valves creates the "dubb"
What causes the lubb dupp heart sounds that are heard while taking a apical pulse?
The closure of mitral and tricuspid valves causes the first heart sound. The second heart sound is produced by the closure of semilunar valves (pulmonic and aortic valves).
What cause the lubb-dupp heart sounds that are heard while talking an apical pulse?
The closing of the valves in the heart. The first sound is caused by the closing of the atrioventricular valves within the heart. The second sound is caused by the shutting of the aortic and pulmonary valves.
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.
