Carbon Dioxide (CO2)
The blood absorbs oxygen from the lungs - enabling it to be transported throughout the body.
The pulmonary artery takes carbon dioxide (CO2) from the heart to the lungs. Oxygen is then carried back to the heart by the pulmonary vein. Finally, the aorta/arteries carry oxygen to the body.
Veins carry blood back to the heart while arterys carry blood away into the body
It's referred to as Carbon dioxide. It is the main cellular waste product that is carried in the blood to the lungs through the heart.
The circulatory system for one needs oxygenated blood to be transported from the lungs to the heart, and it needs the body to get rid of carbon dioxide from the blood through the lungs. :)
Air fills lungs, heart pumps non-oxygenated blood to the lungs via arteries where it becomes oxygenated flows back to the heart and flows through the body .....
