Detailed explanation-1: -These are blood vessels that carry oxygenated blood from the heart to the tissues. These have thick-walled and narrower lumens because they carry blood from the heart with great pressure.
Detailed explanation-2: -Arteries have narrow lumen because the blood from the heart comes into the arteries with a lot of pressure. Due to this reason, arteries are thick walled so that they do not burst. Hence, to maintain the same pressure, arteries have narrow lumen.
Detailed explanation-3: -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-4: -The cavity or channel within a tube or tubular organ such as a blood vessel or the intestine.
