A molecule of CO₂ is released into the blood in your brain.  Select the correct path of this CO₂ through the circulatory system into the lungs.  Not all locations are listed and the CO₂ is immediately exhaled after it reaches the lungs. 

 

Superior vena cava -> right atria -> tricuspid valve -> pulmonary vein

inferior vena cava -> right atria -> bicuspid valve -> pulmonary artery 

Inferior vena cava -> right atria -> tricuspid valve -> pulmonary artery 

Superior vena cava -> tricuspid valve -> right ventricle -> pulmonary artery

Superior vena cava -> tricuspid valve -> right ventricle -> pulmonary artery
