There are two the superior (from the head) and inferior (from the body) vena cava.
oxygenated blood
The vessel that brings blood back to the right atrium is the superior vena cava and the inferior vena cava.
The two blood vessels that bring blood into the right atrium from the body of a pig are the superior vena cava and the inferior vena cava. The superior vena cava carries deoxygenated blood from the upper body, while the inferior vena cava brings deoxygenated blood from the lower body. Together, they ensure that all systemic blood returns to the heart's right atrium for reoxygenation in the lungs.
right atrium
Superior and inferior Vena Cava
There are no vessels that drain the right atrium, except, perhaps the coronary veins. The right atrium moves blood through the tricuspid valve into the right ventricle of the heart.
The vessels that carry blood to the heart of the blood vessels called veins. Arteries carry blood from the heart to the various body tissues.

The veins. The Inferior and Superior Vena Cavae carry deoxygenated blood towards the heart from the body whereas the pulmonary vein carries oxygenated blood.
There are two the superior (from the head) and inferior (from the body) vena cava.
The vessel that brings blood to the heart from the trunk and pelvic region is the inferior vena cava. It is one of the main blood vessels in the body, responsible for carrying deoxygenated blood from the lower half of the body to the right atrium of the heart.
The superior vena cava and inferior vena cava are the two vessels that return oxygen-poor blood to the heart. Both empty into the heart's right atrium.
