Final answer:
The only artery in the body that carries deoxygenated blood is the pulmonary artery.
Step-by-step explanation:
The only artery in the body that carries deoxygenated blood is the pulmonary artery.
In the circulatory system, the pulmonary artery carries deoxygenated blood from the heart to the lungs for oxygenation through gas exchange.
This is an important distinction as most arteries, including the coronary arteries, carry oxygenated blood to tissues throughout the body.
