Explanation:
Detailed explanation-1: -Arterioles play a significant role in the systemic vascular resistance because of the lack of significant elastic tissue in the walls. The arterioles vary from 8 to 60 micrometers. The arterioles further subdivide into meta-arterioles.
Detailed explanation-2: -A capillary is a blood vessel. It does not have the muscular/elastic tissue of other blood vessels. It has a single celled wall to help substances be transported through organisms. Capillaries are small, and smaller than any other blood vessels.
