Well, I'm not sure if we're talking about the same thing, but I recently learned that there are two kinds of blood (sort of) - blood with oxygen, and blood without oxygen. If the blood with oxygen and the blood that has yet to receive oxygen is mixed, then the person will always be tired. So there's a part in the heart that separates the blood that already received oxygen and the blood that is on it's way to receive oxygen. That part (I forgot what it was called) grows in shortly after birth. I hope we're talking about the same parts.
Aortic Semilunar Valve
This is the "right atrioventricular canal" whose opening contains the right AV valve, also known as the tricuspid valve.
Right Atrium , Left Atrium , Right Ventricle , Left Ventricle
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.
Mitral Valve
Aortic Semilunar Valve
Tricuspid vavle
It is a valve.
It is the valve that lies between the left atrium and the left ventricle in the heart.

there is a tricuspid valve in between the right atria and ventricle.
Mitral Valve
the mitral valve
The four chambers are; Left atrium Right atrium Left Ventricle Right Ventricle The two upper chambers are called atria (singular: atrium) and the two lower chambers are called ventricles. There are four chambers of the heart - the right atrium, left atrium, right ventricle and left ventricle.
The atrioventricular (AV) valve must be open to allow blood to flow from the atrium to the ventricle. This valve ensures one-way flow of blood by opening when the atrium contracts and closing to prevent backflow when the ventricle contracts.
