prevents blood flow from the left ventricle to the left atrium.

Detailed explanation-1: -Separates the top left chamber (left atrium) from the bottom left chamber (left ventricle). Opens to allow blood to flow from the left atrium to the left ventricle. Prevents the back flow of blood from the left ventricle to the left 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: -The bicuspid valve separates the left atrium from the left ventricle. The aortic valve separates the left ventricle from the aorta. These valves separate the chambers of the heart, and prevent back flow from one chamber to the other.
