atrioventricular
The atrioventricular valves are two heart valves that allow for the transportation of blood from the atria to the ventricles of the heart. Its function is to prevent the return of blood to the atrium.
The valve between your RIGHT atrium and ventricle is called the TRICUSPID VALVUE and the valve between your LEFT atrium and ventricle is called the MITRAL or BICUSPID VALVUE.
The upper chambers of the heart are called auricles/atria and the lower chambers of the heart are called ventricles. The valve between the left atrium and the left ventricle is called the Bicuspid valve/Mitral valve. The valve between the right atrium and the right ventricle is called the Tricuspid valve.
Quote from Wikipedia:"Cardiac skeleton (sometimes called "fibrous skeleton of the heart") refers to the structure of dense connective tissue in the heart that separates the atria from the ventricles. It is not a "true" skeleton, but it does provide structure and support for the heart, as well as isolating the electric charges that go through the heart by slowing them down enough to allow the atriums to contract before the ventricles so that the heart is much more efficient. It also allows the valves (bicuspid, tricuspid, semilunar) to keep open by giving them structural support."I do wonder why you didn't google it though...
Yes. They used to be called Siamese twins but that was changed to conjoined twins for political correctness. They are twins that are born joined together by some part of their body due to the egg bot completely separating during pregnancy.

Atrio-ventricular valves
The upper heart valves are called atriums, and the lower heart valves are called ventricles.
There are 4 heart chambers. The two upper chambers are called atria while the two lower chambers are called ventricles. The valve separating the atria from the ventricles is called the atrioventricular valve. Then you would have your right and left atrioventricular valves.

The heart has two types of valves that keep the blood flowing in the correct direction. The valves between the atria and ventricles are called atrioventricular valves (also called cuspid valves), while those at the bases of the large vessels leaving the ventricles are called semilunar valves.
These are called the ventricles
TRUE
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.
The atrio-ventricular valves (or A-V valves) are exactly what their name implies. They are valves located between the atria and ventricles. Since there are two atria and two ventricles, it follows naturally that there must be two A-V valves. The one on the right is called the TRICUSPID valve and the one on the left is called the MITRAL valve.
Atrioventricular valves ar the valves in the heart that lie between the atria and the ventricles. These valves stop the the blood from flowing back (in the wtong direction) from the ventricles into the atria. There are two atrioventricular valves, on the right is the Tricuspis and on the left is the Bicuspid or Mitral valve.
The four valves in the heart are: * the two semi-lunar valves - one at the stem of the aorta, the other is found at the trunk of the pulmonary artery. * The tricuspid valve is on the right-hand side of the heart. * The bicuspid valve is on the left side of the heart.
