Quizplus · Accepted Answer

Arterioles act as resistance vessels primarily due to the contractile activity of their vascular smooth muscle. By constricting or dilating, they are able to regulate blood flow to specific tissues or organs. The thick layer of connective tissue in arteriolar walls provides structural support, while large pores in the walls are not a characteristic feature of arterioles. Arterioles are not particularly elastic vessels and are not as capable of stretching and storing blood as veins.
