Which blood vessel carries blood toward the heart?

• A. Vein
• B. Artery
• C. Capillary
• D. Venule

Answer: (A)

Blood returns to the heart through veins. Veins are low-pressure vessels that often have valves to help prevent backflow, and they carry blood back to the heart as muscles compress them during movement. Arteries do the opposite by carrying blood away from the heart under higher pressure. Capillaries are the tiny exchange vessels where oxygen and nutrients pass to tissues. Venules are small veins that gather blood from capillaries before it moves into larger veins. So, the vessel that carries blood toward the heart is the vein. Note that in the lungs, the pulmonary veins carry oxygenated blood back to the heart, which still aligns with the general idea of moving blood toward the heart.
