There are two types of blood vessels in the circulatory system of the body: arteries that carry oxygenated blood from the heart to various parts of the body and veins that carry blood towards the heart for purification.hey are tiny branches of arteries that lead to capillaries and help maintain the pressure and blood flow in the body. Venous valves prevent blood from flowing in the opposite direction. Connective tissues make up the outermost layer of a vein which is also known as-tunica adventitia or tunica externa.
Arteries-carry blood away from the heart. (I like to think Arteries Away.) Veins-carry blood to the heart. Capillaries-connect veins and arteries. Arteries are the tubes o â¦ r vessles which carry the blood away from the heart once the blood has been oxygenated by the lungs.tructural similarities between artries and veins are 1) The walls of arteries and veins both contain collagen which makes them strong and durable. 2) They both contain elasti â¦ c fibres which allow them to stretch and recoil.
