What vessels carry blood toward the heart?

Explanation:
Veins carry blood toward the heart. They are the vessels designed to return blood from the tissues back to the heart, typically at lower pressure and with valves to prevent backflow, helping blood move upward against gravity. In contrast, arteries carry blood away from the heart to tissues, with the aorta being the main example. Capillaries are tiny vessels where exchange happens between blood and tissues, connecting the arterial and venous systems. An exception to remember is that the pulmonary veins, though veins, return oxygenated blood from the lungs to the heart. Overall, the vessels that bring blood back to the heart are veins.
