What structural differences are between arteries and veins in the heart
Veins and arteries are both types of blood vessels but arteries carry blood away from the heart to the rest of the body while veins carry blood to the heart from the rest of the body.All arteries except the pulmonary and umbilical arteries carry oxygenated blood while all veins carry deoxygenated blood.rteries, on the other hand, are classified as systemic (part of the cardiovascular system), pulmonary (carry blood to the lungs), aorta and arterioles. Arteries carry bright red blood as it is oxygenated while veins have the dark red blood. Arteries progressively divide into smaller tubes unlike veins.
