The correct order of blood flow is arteries (carry oxygenated blood away from the heart), arterioles (smaller branches of arteries which control blood flow to capillaries), capillaries (exchange of oxygen, nutrients, and waste products with tissues), venules (small veins that collect blood from capillaries), and veins (carry deoxygenated blood back to the heart).  Therefore, option C - arteries, arterioles, capillaries, venules, veins - is the correct order of blood flow.
