Vena Cava Aorta
Pulmonary Artery Pulmonary Vein
Liver and Kidney
Carries blood away from the heart.
Thick muscle - high pressure blood flow
Elastic tissue allows streching during heart beat pulses.
Carries blood to the heart.
Valves - prevent backflow of blood (low pressure)
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.
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.
