Oxygenated Blood is carried away from the heart  to other parts of the body by

•  Pulmonary veins
  

•  Pulmonary artery
  

• Aorta

• inferior vena cava

What is the function of heart valves?

• To prevent blood from flowing back into ventricles

• permit blood to circulate rapidly

• stop the circulation whenever necessary

• prevent blood from moving rapidly

All of the following are correct about the

normal direction of blood flow EXCEPT
