Deoxygenated blood from the body flows into the right side of the heart via the Vena Cava.

The circulatory system involves two main loops: the systemic circulation (body) and the pulmonary circulation (lungs). Deoxygenated blood returns from the body via the superior and inferior vena cava to the right atrium, then to the right ventricle, which pumps it to the lungs.

Oxygenated blood returns from the lungs via the pulmonary veins to the left atrium, then to the left ventricle, which pumps it to the body via the aorta. Therefore, the aorta, pulmonary vein (carrying blood *from* lungs), and left atrium all carry oxygenated blood (with the pulmonary artery and vena cava carrying deoxygenated blood as key exceptions to the typical vein/artery oxygenation rule).
