What is the difference between lub and dub?
The difference between lub and dub (The heart sounds S1 and S2 of a heartbeat) is that the lub occurs when atrioventricular valves close, and dub occurs when the aortic and pulmonary valves close (valves leading out of the heart from the left and right ventricles).
What is the major difference between arteries and veins?
Arteries carry blood away from the heart. Veins return blood to the heart.
Where else in the circulatory system are valves found?
Valves can be found in the heart. They sit between the Atria and the Ventricles and help aid cardiovascular activity.
Is there any difference between the heart pumping blood and the heart beating?
Yes the "heart beat" is just the sound of the valves opening and closing, not the sound of the blood being pumped.
Valves of the heart open and close due to?
Due to pressure changes in different chambers of the heart. For example, when the atria contract, the bicuspid and tricuspid valves open. They get closed, when the ventricles contract. When the ventricles contract the aortic and pulmonary valves open. Aortic and pulmonary valves close, when the ventricles relax.
Is there a difference between liquid check valves and gas check valves?
Yes
What do the AV valves in the heart do?
It means "atrioventricular". It refers to the valves between the atria and the ventricles.
How can you distinguish between an atrioventicular valve and a semivunar valve in the heart?
The atrioventricular valves are located between the atria and the ventricles. The semilunar valves are located between the ventricles and the arteries leaving the heart.
How is the heart created?
Heart sounds are created by the relationship between the valves of the heart and the surface of the thorax.
What is the difference in heart sounds?
lub dub lub is when the av valves close and dub is when the semi lunar valves close
Closing of the AV valves produces the?
The AV valves lie between the atria and the ventricles of the heart. The closing of these valves produces the lub-dub sound heard when the heart is auscultated.
What is a heart's lub-dub?
They are the representation of the heart's sounds, one made by interior valves closing and one by the exterior valves at the exit of the ventricles.Lub: Valves closing between atria and ventricles.Dub: Aortic and pulmonary valves closing (semilunar valves).
