Explanation:
Blood moves from the heart through arteries and then into progressively smaller vessels before reaching the capillaries. The small vessels that carry blood away from the heart and connect arteries to capillaries are arterioles. Their muscular walls allow them to constrict or dilate, helping regulate blood flow and pressure as blood moves toward tissues. Capillaries are the exchange vessels that come after arterioles, connecting them to venules where blood returns toward the heart. The aorta is the main artery that leaves the heart, while veins carry blood back to the heart, not away from it.
