Arterioles have an average diameter of 30 µm, they have thin adventitia, and their media is often incomplete which means they have fewer smooth muscle cells than muscular arteries. Venues typically have an even thinner wall and capillaries have a much smaller diameter. Elastic arteries, on the other hand, have a much larger diameter and a thick media layer.
