The Mitral valve.
The valve that prevents blood from returning to the left ventricle is called the "mitral valve" it is also known as the "bicuspid valve" as it has two flaps.
The mitral valve gets its name from resemblance of a "bishops mitre" (hat).
Back-flow is prevented by the closing of the Atrioventricular (Mitral) valve.
The mitral valve, also known as the bicuspid valve, controls the flow of blood from the left atrium to the left ventricle. The mitral valve is one of the two atrioventricular valves. The other, on the right side of the heart, is the tricuspid valve.
Mitral Valve
The aortic valve
The bicuspid valve is the valve between the atrium and ventricle on the left side of the heart. It ensures that blood flows in the correct direction - when the ventricle contracts, it prevents the blood from flowing backwards into the atrium.
The interatrial septum separates the right and left atria. This wall prevents the mixing of oxygen-rich and oxygen-poor blood.
Aortic Semilunar Valve
Contraction of the left ventricle results in the blood being pumped out into the Aorta (through the Aortic Valve) where it is then sent to all the body's arteries. The mitral valve prevents blood flowing into the left atrium when the ventricle contracts.
This is the "right atrioventricular canal" whose opening contains the right AV valve, also known as the tricuspid valve.

Aorta
you mean left atria to left ventricle? the bicusped/mitral valve
The right atrioventricular valve (or right AV valve), also called the tricuspid valve, (for its three leafletlobes) controls the flow of blood between the right atrium and right ventricle. (The opening itself is the "right atrioventricular canal.") It prevents dexoygenated blood from regurgitating back into the right atrium. The vale is called "tricuspid" because of its three leaflets; it must be noted however, that the tricuspid valve can contain between two and four leaflets.
Tricuspid vavle
The right atrioventricular valve (or right AV valve), also called the tricuspid valve, (for its three leafletlobes) controls the flow of blood between the right atrium and right ventricle. (The opening itself is the "right atrioventricular canal.") It prevents dexoygenated blood from regurgitating back into the right atrium. The vale is called "tricuspid" because of its three leaflets; it must be noted however, that the tricuspid valve can contain between two and four leaflets.
Opening/closing of leaf pores (stoma) has the purpose to control evaporation.
the biscuspid valve works as a trap door opening when the oxygented blood needs to pass to the left ventricle
