It means "atrioventricular". It refers to the valves between the atria and the ventricles.
What else can I help you with?
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 can be a condition where the AV valves don't close?
a heart murmur
What does the s1 sound of the heart signifies?
It signifies the closure of AV valves.
What are the string-like structures that attach to the atrioventricular valves of the heart?
Chordae tendinae are the string-like structures that attach to the AV valves of the heart.
What do the letters AV represent in describing heart valves?
It means "atrioventricular". It refers to the valves between the atria and the ventricles.
What part of the heart act like a dam which control blood flow in the heart?

What is the difference in heart sounds?

What are the fibrous threads connecting the AV valves to muscles in the heart wall?
Chordae Tendinae
What is an AV valve in the heart?
The AV or atrioventricular valves are the valves which separate the upper chambers (the atria) from the lower chambers (ventricles) of the heart. The AV valve on the left side of the heart is known as the left atrioventricular (AV) valve or the mitral valve. The AV valve on the right side of the heart is known as the right atrioventricular (AV) valve or the tricuspid valve.
What happens to A-V valves during ventricular contraction?
As the ventricles of the heart contract the pressure in the ventricles rises beyond that of the atria. This pressure differential causes the AV valves to shut.
What causes the lub and dup of the heart?
The lub is caused by the closing of the AV valves. The dup is caused by the semilunar valves closing at the end of systole.
