aorta
The major vein that leads into the right atrium is the vena cava. The superior vena cava carries deoxygenated blood from the upper part of the body into the right atrium. The inferior vena cava carries deoxygenated blood from the lower part of the body into 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.
The superior vena cava supplies the deoxygenated blood from the upper half of the body into the right atrium
Blood returning to the right atrium of the heart is deoxygenated.
right atrium
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
right atrium
it goes from the right atrium to the right ventricle
Four chambers, left ventricle, left atrium. The right atrium and ventricle ( send blood to the lungs ). There are valves that stop the blood from backing up into the atria and the veins. And there are coronary arteries. There's a few more miscellaneous parts, but that covers the major stuff.
