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.
The first heart sound is heard when?
S1 which is the closing of the atrioventricular 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.
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 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 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 makes the first sound of a heartbeat?
The first sound of a heartbeat is caused by the closing of the atrioventricular valves (mitral and tricuspid valves) in the heart and marks the beginning of ventricular systole, where the ventricles contract to pump blood. This sound is known as the "lub" sound of the heartbeat.
Where does the sound of your heart pumping blood come from?
heart valves opening and closing
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.
What is normal heart sounds heard while the heart is working?
Valves opening and closing and blood flowingThe normal action of the heart, the pumping of the chambers and the closing of the valves.Closing of the valvesLub = closing the AV valvesDub = closing of the semi lunar valvesThe heart beats when the blood pumps
The sound you hear when you listen to your heart with a stethescrope is actually what?
The valves in your heart opening and closing.
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.
