An arteriole is a small-diameter blood vessel in the microcirculation that extends and branches out from an artery and leads to capillaries. Arterioles have muscular walls and are the primary site of vascular resistance. The greatest change in blood pressure and velocity of blood flow occurs at the transition of arterioles to capillaries.
The structure of an arteriole is:             Arterioles are tiny branches of arteries that lead to capillaries.   These are also under the co â¦ ntrol of the sympathetic nervous system, and constrict and dialate, to regulate blood flow.rterioles are small diameter vessels that branch off of your arteries. They inevitably connect arteries to capillaries. You can find them pretty much anywhere in your body.
