It is brought back to the heart to be pumped through the lungs to be exhaled.
The carbon dioxide diffuses into the plasma portion of the blood and is carried to the heart. From there it is carried to the lungs where it is released when you exhale.

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.
exhaled
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.
The aorta carries oxygen-rich blood from the heart to all parts of the body except to the lungs. Oxygen-poor blood is carried to the lungs from the heart through the pulmonary artery.
As the blood passes though the pulmonary circulation, oxygen within the lungs binds with the hemoglobin and is carried from the lungs back to the heart and then from there on to the active tissues of the body.
Deoxygenated blood is carried to the right side of the heart. This blood has returned from the body and is low in oxygen content, ready to be pumped to the lungs for oxygenation.
