Blood vessels that carry blood toward the heart are called?

• A. Veins
• B. Arteries
• C. Capillaries
• D. Arterioles

Answer: (A)

Blood vessels that carry blood toward the heart are veins. Veins form the return path for blood after it has circulated through the body and tissues. In the systemic circuit, they typically carry blood back to the heart with lower pressure, and valves inside many veins help prevent backflow as muscles contract and push blood along. The journey toward the heart begins at small venules and continues through larger veins until the blood reaches the heart’s atria. Arteries, in contrast, carry blood away from the heart, while capillaries are the tiny vessels where exchange of oxygen, carbon dioxide, and nutrients with tissues occurs. Arterioles are the smaller branches of arteries that feed into capillaries.
