The prominent abnormalities are usually seen in the small muscular arteries and arterioles. The tunica media, which is composed of smooth muscle, undergoes hypertrophy (increased cell size), and the tunica intima undergoes hyperplasia (increased number of cells).

The large arteries that leave the heart taper down to smaller arteries called arterioles. The arterioles then taper down into smaller vessels called capillaries, which supply the much-needed oxygen and nutrients to the many organs of the body The blood then returns to the heart through the veins.
A complex system of hormones, nerve signals, and other elements regulates the blood flow by widening and constricting small blood vessels called arterioles. Blood pressure normally fluctuates not only with each heartbeat, but according to your level of physical activity, the time of day, your anxiety level, and other factors.
