ARTERIOL/O refers to which vessel?

Explanation:
Arteriol/o designates the arteriole, the small vessel between arteries and capillaries. Arterioles have muscular walls that can constrict or dilate to regulate blood flow and resistance, making them the tiny branches that feed capillary networks. This distinguishes them from larger arteries (arteries), the tiny capillaries (capillaries), or the main exit from the heart (the aorta).
