atrioventricular
Yes, atrioventricular valves are located between the atria and the ventricles in the heart. These valves prevent blood from flowing back into the atria when the ventricles contract. The two main atrioventricular valves are the tricuspid valve on the right side and the mitral valve on the left side.
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 cone-shaped muscular pillars in the ventricles are called papillary muscles. These muscles help anchor the chordae tendineae, which are thin bands that connect the papillary muscles to the heart valves (mitral and tricuspid valves) to prevent them from prolapsing back into the atria during contraction.
There are atrioventricular valves on each side of the heart that keep blood from flowing from the ventricles back up into the atria. There are also semilunar valves that prevent blood from flowing from the pulmonary arteries and aorta back into the right and left ventricles, respectively.
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.

Atrio-ventricular valves
The upper heart valves are called atriums, and the lower heart valves are called ventricles.
The valves that control the exits of the ventricles are called semilunar valves. There are two semilunar valves: the aortic valve, which regulates blood flow from the left ventricle into the aorta, and the pulmonary valve, which controls blood flow from the right ventricle into the pulmonary artery. These valves prevent backflow of blood into the ventricles after contraction.
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.
Yes, atrioventricular valves are located between the atria and the ventricles in the heart. These valves prevent blood from flowing back into the atria when the ventricles contract. The two main atrioventricular valves are the tricuspid valve on the right side and the mitral valve on the left side.
