Review Vasculature…Almost ALL Arteries:
– Carry oxygenated blood away from the heart
– Carry oxyhemaglobin blood to organsAlmost ALL Veins:
– Carry deoxygenated blood to the heart

organsExceptions:
– Portal vein-• Carries deoxyhemaglobin to the liver
– Pulmonary veins-• Carries deoxyhemaglobin to the
lungs– Pulmonary arteries-
• Carries oxyhemaglobin to the heart
