Which vessel carries blood away from the heart?

Explanation:
The directional flow of blood relative to the heart is what this item tests. Arteries carry blood away from the heart, propelled by the heart’s pumping action. In systemic circulation, oxygen-rich blood leaves the heart via arteries and travels to tissues. Veins return blood to the heart, capillaries are the exchange vessels between blood and tissues, and lymphatics carry lymph rather than blood. The same rule applies to the pulmonary circuit: the pulmonary artery carries blood away from the heart to the lungs, and the pulmonary veins bring it back. So, the vessel that carries blood away from the heart is the artery.
