Which vessel carries blood toward the heart?

Explanation:
Blood returns to the heart through veins. Veins are the vessels whose main role is to carry blood back to the heart, whereas arteries carry blood away from the heart and capillaries serve as the exchange links between them. The aorta is a major artery that transports blood out of the heart to the body. Veins, including the systemic veins returning to the right atrium and the pulmonary veins bringing oxygenated blood to the left atrium, are defined by this back-to-the-heart flow. Their thinner walls and valves help ensure blood moves in the right direction under lower pressure.
