right ventricle and right atrium
The interatrial septum separates the left atrium from the right atrium (the atria are the upper chambers of the heart).
Upper chambers of heart are the left and right atrium Lower are the left and right ventrical atrioventricular valves separate the two. Bicuspid (mitrial) valve separates the left atrium/ventrical and the tricuspid separates the right atrium/ventrical.
1)Tricuspid valve separates the right atrium from the right ventricle 2) Pulmonary (semilunar) valve separates the right ventricle from the pulmonary trunk leading to the pulmonary arteries 3) Bicuspid (Mitral) valve separates the left atrium from the left ventricle 4) Aortic valve separates the left ventricle from the aorta

The AV valve. There is one for the right and left sides of the heart.
The bicuspid valve, also known as the mitral valve, separates the left atrium from the left ventricle in the heart.
The interatrial septum separates the left and right atria.
for the right atrium and right ventricle, the tricuspid valve separates the two. For the left, the mitral valve separates the two.
The right atrium receives de-oxygenated blood from the body through the superior vena cava and inferior vena cava. The tricuspid valve, which separates the right atrium from the right ventricle, opens to allow the de-oxygenated blood collected in the right atrium to flow into the right ventricle.
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.
