left atrium to the right atrium

|
right atrium to the left atrium
|
Detailed explanation-1: -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-2: -When the ventricular walls contract (specifically, the walls of the left ventricle), the bicuspid/mitral valve closes to prevent blood from flowing into the left ventricle from the left atrium, when the left ventricle relaxes, the bicuspid valve opens to allow blood to flow from the left atrium into the left ventricle.
Detailed explanation-3: -Tricuspid Valve 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.
