  • tough fibrous outer layer resisting pressure from within and without
    • muscle layer that can contract to control the flow of blood
      • elastic layer that recoils to help maintain blood pressure
        • thin inner lining (endothelium) that is smooth to reduce friction and thin to allow diffusion
          • lumen- the central cavity of the blood vessel that blood flows through
