Which vessels carry blood away from the heart and are high in oxygen?

• A. Veins
• B. Capillaries
• C. Cardiovascular system
• D. Arteries

Answer: (D)

Arteries are the vessels that carry blood away from the heart. In the systemic circulation they transport oxygen-rich blood from the left ventricle through the aorta to tissues throughout the body, which is why they’re associated with high oxygen content. Veins carry blood back to the heart, and capillaries are tiny exchange vessels between arteries and veins. The cardiovascular system refers to the entire system, not a single vessel type. A useful nuance is that, in the pulmonary circuit, arteries move blood to the lungs and carry it away from the heart even though it’s low in oxygen, but in the systemic context arteries are the oxygen-rich vessels carrying blood away from the heart.
