Vessels of the circulatory system ARTERIES Carry oxygenated blood away from the heart to the capillaries Elastic, muscular and thick-walled Transport blood under very high pressure Arteries > arterioles > capillaries 2.01 Remember the structures of the circulatory system 3

Vessels of the circulatory system VEINS Carry deoxygenated blood away from capillaries to the heart Veins contain a muscular layer, but less elastic and muscular than arteries Thin walled veins collapse easily when not filled with blood Veins have valves that permit flow of blood only in direction of the heart Veins < Venules < Capillaries 2.01 Remember the structures of the circulatory system 7

Pulse Rate and Questions Use page 431 in Red Book for Step by Step Instructions What was the most difficult pulse to find? Which pulse point was the strongest, why? Which was the weakest, why? Which pulse point do physicians/nurses use most commonly, why? Pulse Location Where is this pulse point?
