By definition arteries always carry blood away from the heart and veins carry it to the heart.
Most arteries carry blood with the least amount of carbon dioxide. But there is an exception. The arteries that carry blood to the lungs is very high in carbon dioxide.
The pulmonary vein contains blood with the lowest carbon dioxide content because it carries oxygenated blood from the lungs back to the heart.
The answer is the vein
Capillaries carry carbon dioxide away from cells where it reacts with water to form a bicarbonate ion which is more dissolvable in blood than CO2.
The haemoglobine found in the red blood corpuscles carries the carbon dioxide in the form of carboxyhaemoglobin .
Blood comes into the heart from the systemic circuit. It is low in oxygen. It comes by way of the inferior and superior vena.
When hemoglobin carries carbon dioxide, it forms carbaminohemoglobin. This occurs in the red blood cells as carbon dioxide is transported from the tissues to the lungs to be exhaled.
Respiration is the process that carries oxygen to the cells and removes carbon dioxide from them. Blood carries the oxygen to the cells.

Ariel zapata.... its the lungs.... that's how we breath... in with the oxigen out with the carbon dioxide, i got myspace. for further queations...
Blood carries carbon dioxide out of cells.
It carries carbon dioxide and oxygen.
