Where does the right atrium receive deoxygenated blood from?
  1. Superior vena cava
  2. Inferior vena cava
  3. Both A and B
  4. Neither A nor B
Explanation
Answer - C - The right atrium receives deoxygenated blood from the superior and inferior vena cava. The blood is then moved to the right ventricle by atrial contraction and gravity. The right ventricle perfuses the blood through the lungs for oxygenation. After being received by the left atrium and delivered to the left ventricle, it is pumped to the body.
