Which vessels carry oxygenated blood away from the heart?

Explanation:
Oxygenated blood is carried away from the heart by the arteries. The left ventricle pumps this blood into the aorta, the main artery, and from there into its branches to supply the body's tissues with oxygen-rich blood. A key detail is that, while most arteries carry oxygenated blood, the exception is in the pulmonary circulation—pulmonary arteries carry deoxygenated blood away from the heart to the lungs. Lymphatics are not blood vessels, and capillaries are the site of exchange rather than the main carriers away from the heart. So the vessels that carry oxygenated blood away from the heart are arteries, with the aorta and its branches as the primary example.
