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 are artrioventricles?
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.
What structures works to prevent prolapse of the atrioventricular valves?
The papillary muscles and the chordae tendinae work to prevent prolapse of the AV valves. This prevents backflow of blood in the heart.
What valves prevent blood from flowing backwards from the arteries into the heart?
All the valves of the heart prevent backflow of the blood through the heart: tricuspid valve, pulmonary valve, mitral valve, and aortic valve. Furthermore, there are one-way valves in the veins that prevent backflow of blood.
Do valves in the heart let the blood travel in all directions?
No the way the valves of the heart are set up causes the blood to move in one direction only.
