Quizplus · Accepted Answer

Oxygen-poor blood is carried from the heart of a mammal to the lungs via the pulmonary arteries. The pulmonary arteries are the only blood vessels that carry deoxygenated blood away from the heart and to the lungs for oxygenation. The pulmonary veins, superior vena cava, and inferior vena cava all carry oxygenated blood towards the heart.
