Blood vessels that carry blood toward the heart are called?

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

Answer: (A)

Blood vessels that carry blood toward the heart are veins. They form the return pathway in circulation, collecting blood from tissues after it has passed through capillaries and guiding it back to the heart. Veins have valves to prevent backflow and operate under relatively low pressure, with thinner walls. In contrast, arteries carry blood away from the heart and have thick, muscular walls to withstand high pressure. Capillaries are the tiny exchange vessels between arteries and veins, and the aorta is the main artery leaving the heart. In pulmonary circulation, veins still return blood to the heart (carrying blood that’s now oxygenated from the lungs).
