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
