Explanation:
Detailed explanation-1: -The tunica adventitia is the outermost layer and consists of connective tissue and elastic fibers that provide the vessel’s strength. In large veins, this may be the thickest layer.
Detailed explanation-2: -Capillaries are thin-walled vessels composed of a single endothelial layer. Because of the thin walls of the capillary, the exchange of nutrients and metabolites occurs primarily via diffusion. The arteriolar lumen regulates the flow of blood through the capillaries.
Detailed explanation-3: -Capillaries. Capillaries are tiny, extremely thin-walled vessels that act as a bridge between arteries (which carry blood away from the heart) and veins (which carry blood back to the heart).
