Answer 1

Answer:

human heart

Explanation:

Humans have a four-chambered heart with complete separation between oxygenated and deoxygenated blood.  

The right auricles receive deoxygenated blood from vena cava or big veins. The right ventricle pumps deoxygenated blood to the lungs for oxygenation through the pulmonary artery.  

Thus right auricle, right ventricle, and pulmonary artery contain deoxygenated blood
