Muscular and Elastic Artery Arteriole

Muscular arteries like femoral or radial distribute blood flow via thick tunica media of smooth muscle regulating resistance through vasoconstriction or dilation, elastic arteries like aorta buffer pulsatile flow with abundant elastin in laminae absorbing systolic pressure, while arterioles with precapillary sphincters control capillary perfusion and systemic resistance.
