Explanation:
Detailed explanation-1: -Hint: Capillaries are very thin blood vessels. They connect arteries and veins. The hollow opening inside the blood vessel is called lumen.
Detailed explanation-2: -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-3: -Vessels that, when relaxed, measure <400 m in lumen diameter act as the major site of vascular resistance and include a network of small arteries (lumen ≈100 to 400 m) and arterioles (<100 m).
