Narrow Lumen Thick muscle - high pressure blood flow Oxygenated blood Elastic tissue allows streching during heart beat pulses. 3 of 6 Vein Carries blood to the heart. Large Lumen Little Muscle Valves - prevent backflow of blood (low pressure) Deoxygenated 4 of 6 Capillaries Wall is one cell thick. Carries blood all over organs. Wall are permeable to most molecules and the pressure is very high so materials are forced through the wall --> tissue fluid. 5 of 6 Tissue Fluid Flows around the tissues surrounding the capillaries, delivering glucose and oxygen to the cells. Takes away CO2 and other metabolic waste products. Excess tissue fluid returns to the blood via the lymphatiic system. Tissue fluid forms because:Hydrostatic pressure in the capillaries forces liquid out. 6 of 6
