Explanation Both the arteries as well as veins are made up of three layers or tunics, which are tunica intima, tunica media, and tunica externa, from inside out. The functions of three tunics are described below: Tunica intima: In arteries as well as veins, tunica intima consists of endothelium layer and loose connective tissues. Arteries contain one extra layer in this tunic, which is known as the internal elastic lamina. Its function is to provide a smooth surface, which will reduce the friction of blood and vessel. Tunica media: The larger tunica media in arteries help the artery to expand and accommodate blood during systole and recoil to the normal position during diastole...
