Which vessel carries blood toward the heart?

Explanation:
Blood return to the heart happens through veins. Veins are the vessels that carry blood toward the heart, often with the help of one-way valves and the surrounding muscle movements to push blood back up, especially from the limbs. They operate under lower pressure than arteries, which is why these valves and muscular assistência are important for maintaining forward flow. In contrast, arteries carry blood away from the heart under higher pressure, arterioles are the smaller arteries leading to capillaries, and capillaries are the sites of exchange where blood delivers oxygen and nutrients and picks up waste. So the vessel that best fits “carries blood toward the heart” is the vein.
