The vascular circuit that connects the right atrium to the left atrium is the pulmonary circulation.
The pulmonary circuit is blood flow movements from the pulmonary trunk to the left atrium...while the systemic circuit is a continuation from the left atrium all the way to the right atrium.......... Disclaimer [research for detailed blood movements in pulmonary circuit and systemic circuit if this isn't enough].
well you have two atria the right atrium and left atrium but i think the right atrium has deoxygenated blood and the left atrium has oxygenated blood.
Atrium
After it makes its circuit throughout the body, blood must return to the heart. the veins carry the blood back toward the heart via the superior and inferior vena cava. The vena cava empty into the right atrium of the heart to begin the cycle again.
The atrium does not carry gas. Blood flows through it. The blood in the left atrium is oxygenated.
One drop of blood starts in the right atrium -> tricuspid valve-> Rt ventricle -> pulmonary valve -> Pulmonary artery -> lungs where oxygen is picked up and carbon dioxide is dropped off -> Pulmonary vein -> left atrium -> bicuspid valve -> left ventricle -> Aortic valve -> Aorta and then out to the body tissues and systemic circulation. This circuit is called the pulmonary circuit.
Yes, blood from both the inferior and the superior vena cava flow into the right atrium. Blood from the pulmonary veins coming from the lungs flow into the left atrium.

The left atrium receives oxygenated blood from the pulmonary vein.
Are you using this instead of doing homework? Blood comes back into the heart from the lungs via the Pulmonary vein into the Left Atrium.
summary of cuerts during blood circulation
Blood flows from the right atrium of the heart into the right ventricle to the pulmonary artery to the lungs where the blood is oxygenated. From there it flows to the pulmonary vein to the left atrium and ventricle, then to the aorta.
the right atrium via the coronary sinus
The circulation of venous blood from the right ventricle of the heart to the lungs and back to the left atrium of the heart.
Atrium
An atrium is in the heart, it is the top two chamber of the heart. the right atrium deals with deoxygenated blood from the body, whereas the left atrium deals with oxygenated blood from the lungs.
