Answer:
Arterioles
Step-by-step explanation:
Arterioles are the end points of the arteries and these are also called resistance arteries because of small diameter and thick muscular walls. Due to this property, the lumen of the arterioles gets narrowed in comparison to other arteries and thus they provide greatest resistance to the blood flow. As these arteries are small, they are involved in the regulation of local blood flow in each and every part of the body.
