PPT-Arteries

and Veins Learning Outcomes Arteries have an outer layer of connective tissue containing elastic fibres and a middle layer containing smooth muscle with more elastic fibres The elastic walls of the arteries stretch and recoil to accommodate the surge of blood after each contraction of the heart The smooth muscle can contract or relax causing vasoconstriction or vasodilation to control blood flow.
