Incorporated, a worldwide network of science museums and related institutions.
*****************************************************************************

An exception: blood flowing from the right side of the heart to the  
lungs in the pulmonary arteries carry deoxygenated blood (dark red),  
and pulmonary veins carry oxygenated blood (bright red). In the  
fetus, the umbilical artery also carries deoxygenated blood. The  
major function of the right side of the heart is to pump blood to the  
lungs to become oxygenated. Arteries carry blood away from the heart.
