prevent blood from leaking back into the atria

|
|
allow blood to flow into the atria

|
|
allow blood to leave the ventricles
|
Detailed explanation-1: -Separates the top right chamber (right atrium) from the bottom right chamber (right ventricle). Opens to allow blood to flow from the right atrium to the right ventricle. Prevents the back flow of blood from the right ventricle to the right atrium.
Detailed explanation-2: -When the ventricles contract, the blood should go out of the heart and not back to the atrium. This backflow of blood is prevented by valves. Tricuspid valve prevents backflow of blood from right ventricle to right atrium. Bicuspid valve prevents backflow of blood from left ventricle to left atrium.
Detailed explanation-3: -Two of the valves, the mitral and the tricuspid valves, move blood from the upper chambers of the heart (the atria) to the lower chambers of the heart (the ventricles). The other two valves, the aortic and pulmonary valves, move blood to the lungs and the rest of the body through the ventricles.
Detailed explanation-4: -Tricuspid valve (guards the opening between the right atrium and right ventricle) Bicuspid valve or Mitral valve (guards the opening between the left atrium and left ventricle)
