Which artery carries the deoxygenated blood from heart to lungs?

The pulmonary artery is the only artery in the human body that carries deoxygenated blood. It transports blood from the right ventricle of the heart to the lungs, where the blood is oxygenated through the process of respiration. Once the blood is oxygenated, it returns to the heart through the pulmonary veins, which carry oxygenated blood.
