Explanation:
Detailed explanation-1: -The middle layer, the tunica media, is primarily smooth muscle and is usually the thickest layer. It not only provides support for the vessel but also changes vessel diameter to regulate blood flow and blood pressure.
Detailed explanation-2: -Arterioles play a significant role in the systemic vascular resistance because of the lack of significant elastic tissue in the walls.
Detailed explanation-3: -Specifically, arterial bleeding comes out in spurts, venous bleeding flows steadily, and capillary bleeding trickles from the body. Bleeding from the arteries and veins can be severe.
