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
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 the beating sound of your heart come from?
The sound of a heart beat is caused by the closing of the valves in the heart.
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.
The first heart sound lub is caused by what?
The "lubb" sound is produced when the atrioventricular valves in the heart close.
What part of the heart makes the heart sound?
It is caused by the veins in the heart open and close
Prolonged heart sound caused by incomplete closure of heart valves?
murmur
What is abnormal heart sound caused by improper closure of the heart?
murmurmurmurA murmur is a heart sound caused by turbulent blood flow resulting from an abnormal heart valve that either does not close appropriately or does not open normally.
What is an abnormal prolonged heart sound caused by incomplete closure of heart valves?
Abnormal heart sound caused by improper closure of heart valve is called a murmur. A murmur is caused by turbulent blood flow, when a heart valve either fails to open normally or fails to fully close.
What is emptying after the second heart sound?
My bladder.
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.
The normal heart sounds heard through a stethoscope are caused by the contractions of the ventricles?
Normal heart sounds (often called lub-dub) are caused by the pressure changes in the ventricles closing the various heart valves. The first sound, lub, is caused by the closing of the atrioventricular valves after the ventricles have filled with blood and as the ventricles begin to contract. The second sound, dub, is caused by the closing of the semilunar valves as the ventricles relax after pushing blood forward.
