Carbon dioxide is a waste product carried by the veins back to the heart.
The right upper chamber (atrium) takes in deoxygenated blood that is loaded with carbon dioxide. The blood is squeezed down into the right lower chamber (ventricle) and taken by an artery to the lungs where the carbon dioxide is replaced with oxygen.
The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide.
