Which vessels carry blood to the heart?

Explanation:
Veins are the vessels that carry blood toward the heart. Their job is to return blood from tissues back to the heart so it can be pumped again. Arteries do the opposite, moving blood away from the heart under higher pressure, while capillaries are the tiny exchange sites between arteries and veins. Lymphatics carry lymph, not blood. (Note: in the lungs, pulmonary veins return oxygenated blood to the heart, a reminder that veins can carry blood with different oxygen levels depending on the circuit.)
