The artery that comes out of the heart and goes to the lungs. Technically it is an artery since it is coming out of the heart, but the blood is rich in CO2 yet, since it hasnt been oxygenated.

Blood rich in carbon dioxide is pumped from the heart into the lungs through the pulmonary arteries. (Arteries are blood vessels carrying blood away from the heart; veins are blood vessels carrying blood to the heart.)
2. In the lungs, CO2 in the blood is exchanged for O2.
3. The oxygen-rich blood is carried back to the heart through the pulmonary veins.
4. This oxygen-rich blood is then pumped from the heart to the many tissues and organs of the body, through the systemic arteries.
5. In the tissues, the arteries narrow to tiny capillaries. Here, O2 in the blood is exchanged for CO2.
6. The capillaries widen into the systemic veins, which carry the carbon-dioxide-rich blood back to the heart.

Pulmonary artery is rich in CO2 and the Pulmonary vein is rich in O2

Pulmonary circulation is reversed. The pulmonary arteries carry oxygen poor blood to the lungs. Pulmonary veins bring oxygen rich blood to the heart. It is the only exception in the body.
