Structure and Function vessels

STRUCTURE & FUNCTION OF…. Arteries Take Blood AWAY from the heart Thick muscular walls (high pressure) Elastic Usually carry oxygenated blood (except the pulmonary artery) Arteries-Arterioles-Capillaries

STRUCTURE & FUNCTION OF…. Capillaries Walls one cell thick to allow Diffusion of; oxygen(O2) TO the muscle, and carbon dioxide (CO2) FROM the muscle

STRUCURE & FUNCTION OF…. Veins Take Blood TOWARDS the heart Thin walls Non-Return valves Usually carry deoxygenated blood (except the pulmonary vein) Capillaries-Venules-Veins
