Answer:
elastic arteries, muscular artery, arterioles, capillary, venules, medium veins, large veins,
Explanation:
There are three types of blood vessels a) arteries b) capillaries and c) Veins. Arteries are responsible for carrying blood from heart to all other parts of the body. The arteries arising from heart are large in size which then keep on branching and becoming small enough for cellular exchange.
Capillaries are intermediary to veins and the arteries as they allow exchange of nutrient and release of waste product to and from from cells.
Lastly, veins carry deoxygenated blood from organs to the heart. Vieins become larger in size as they get close to heart.
Hence, the correct order is
elastic arteries, muscular artery, arterioles, capillary, venules, medium veins, large veins,
