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.
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 inferior and superior vena cavae bring deoxygenated blood back to the heart from the rest of the body. From there it goes through the heart, to the lungs, back through the heart, then to the body.
The pulmonary veins bring oxygenated blood from the lungs to the left atrium of the heart.
Deoxygenated blood return form the body to the heart via the Superior and Inferior Vena Cavas, which join together to enter the Heart's Right Atrium.
Veins.
Pulmonary veins carry oxygenated blood from the lungs to the left atrium of the heart. Systemic veins return deoxygenated blood from the rest of the body to the right atrium of the heart. Blood vessels carry blood from the heart to all areas of the body.
Heart (Left Ventricle) -> Arteries -> Arterioles -> Capillaries -> Venules -> Veins -> Heart (Right Atrium)
Veins carry deoxygenated blood towards the heart and arteries carry oxygenated blood from the heart to the rest of the body. There is one exception however. Pulmonary veins carry deoxygenated blood away from the heart towards the lungs and pulmonary arteries carry oxygenated blood towards the heart.
They are called Veins just FYI the blood vessels that bring blood away from the heart are called arteries
The heart and your blood vessels
Arteries are the major blood vessels that carry blood away from the heart. Except for the pulmonary arteries which go from the atrium to the lungs, arteries carry oxygenated blood. The veins bring blood back into the heart. Except for the pulmonary veins that connect the lungs to the ventricles of the heart, veins carry deoxygenated blood.
