Explanation / Answer

The three major type of blood vessels are veins,arteries and capillaries

Arteries are blood vessels that carry blood away from the heart Veins carry blood to the heart Arteries carry oxygenated blood except pulmonary artery Veins carry deoxygenated blood except pulmonary vein Structurally arteries have narrow lumen Veins have wide lumen Around the lumen they have thick walls Veins have thin walls around the lumen Arteries donot have valves Veins have one way valves that keep blood flowing towards heart. The arteries divide into smaller branches called arterioles.The artery branches into small capillarie,which have great total cross sectional area than artery. The capillaries connect the arteries to the veins through the venules The movement of blood from arteries to capillaries results in a decrease in the rate of blood flow. As the blood flows from the capillaries into the veins,the total cross sectional area decreases and the rate of blood flow increases Arteries are deeper in flesh than veins Veins are nearer the surface of he skin than arteries Pulse is detectable Generally pulse is not detectable Arteries have thick layer of muscles and elastic fibres Veins have thin layer of muscles and elastic fibres Elasticity of arteries helps to withstand the pulsing of the blood and to maintain pressure Veins depend on skeletal muscle activity to propel blood back to the heart. Blood leaves left half of the heart via single large arterial trunck the aorta,the aorta branches in to many arteries The veins from different organs and tissue unite to form large veins the inferior venacava and the superior vena cava by which blood is returned to the right half of the heart.
