Is blue blood pumped to the heart?

The two largest veins in the body, the superior and inferior vena cava, bring the oxygen-poor (blue) blood to the heart into the right atrium. This oxygen-poor blood then passes through the tricuspid valve into the right ventricle.

Complete answer: Heart sends the impure blood to the lungs for oxygenation. The oxygenated blood means the blood that is rich in oxygen with very less carbon dioxide.
