Hello- Can anyone answer this ? Thank you in advance for your assistance...

If you were a molecule of carbon dioxide, how would you get from the lower arm, back to the lungs to be removed from the body?

The hemoglobin in blood can bind to CO2. The veins in the arm carry deoxygenated/CO2 bound blood towards the heart. From there the pulmonary arteries brings the blood to the lungs for gas exchange.
