Inferior Vena Cava, Superior Vena Cava, Pulmonary veins (left and right)
The nearest organ to the heart that receives oxygenated blood is the lungs. After blood is oxygenated in the lungs, it returns to the heart via the pulmonary veins. From there, the heart pumps this oxygen-rich blood to the rest of the body, including vital organs and tissues.
The heart pumps it. When your heart beats it squeezes blood in the heart into the arteries and from the arteries to the veins and from the veins back into the heart.
Veins carry deoxygenated blood back the heart.
Blood flows away from the heart in arteries, and towards the heart in veins.
Veins are thin. They carry blood to the heart and brain.
Arteries drain (pump blood) into veins. Veins drain into your lungs and heart to be re-oxygenated. (This is not true for veins and arteries to and from your lungs.)
Veins
Veins are blood vessels that carry blood toward the heart.

Veins. Veins carry unoxygenated blood towards the heart.
Veins carry blood back to the heart. In contrast, arteries carry blood away from the heart.
The heart chambers are not called arteries and veins. Heart chambers are atria and ventricles.
