  • The oxygenated blood through pulmonary vein is poured back into the right atrium.

Systemic circulation:

  • It is the pathway in which oxygenated blood from right ventricle flows through aorta to the rest of the body and is brought back into the right atrium by superior and inferior vena cava.

What are the correct statements?

The correct statements:

  • Oxygen-rich blood is carried in the pulmonary veins from the lungs to the left atrium.
  • Oxygen-rich blood is carried in the aorta from the left ventricle to the body.
  • Oxygen-poor blood is carried through the vena cava to the right atrium.
  • Oxygen-poor blood is carried through the inferior and superior vena cava to the right atrium.
