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.
Lymph capillaries resemble blood capillaries somewhat, but differ in important ways. Whereas a blood capillary has an arterial and a venous end, a lymph capillary has no arteâ¦rial end. Instead, each lymph capillary originates as a closed tube. Lymph capillaries also have a larger and more irregular lumen (inner space) than blood capillaries and are more permeable.
