Blood entering the right atrium is deoxygenated and saturated with CO2. Blood that is entering the left atrium has passed through the lungs and is oxygenated. It returns to the left atrium via the pulmonary vein and is saturated with oxygen.

the blood entering the right artrium goes through the blood vessels and ends up in the lungs unlike the left artrium which goes to another organ.
Blood in right ventricle is deoxygenated, while in left ventricle is oxygenated.
deoxygenated blood
The blood enters through the superior and inferior vena cava.
left ventricle Blood enters the left & right atria. Blood entering the left ventricle came from the left atrium. Blood from the body enters the right atrium. From there it is pumped to the right ventricle, through the lungs, to the left atrium, to the left ventricle, then throughout the body. Then back to the right atrium...
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.
Yes, both the superior and inferior vena cava carry deoxygenated (oxygen-poor) blood and deposit it into the right atrium of the heart.
Blood returning to the right atrium of the heart is deoxygenated.
right atrium
From the vena cava, blood travels into the right atrium, then the right ventricle. The right ventricle pumps the blood through the pulmonary arteries to the lungs. The pulmonary vein carries the oxygenated blood back to the left atrium. The blood flows from the left atrium into the left ventricle which pumps the blood through the aorta and to the rest of the body.
In normal human adult physiology, the CO2 concentration in the right atrium is relatively high (typically 46mmHg). In contrast, after exchange in the lungs, blood entering the left atrium has a CO2 concentration of roughly 40 mmHg. This will be different in some heart conditions and fetal circulation.
Two veins return deoxygenated blood to the right atrium. The superior vena cava returns blood from the head and upper body to the right atrium. The inferior vena cava returns blood from the legs and lower body to the right atrium.
Atrium
Are you doing a project or something? Anyway...The right and left atria receive the blood entering the heart.
