Capillaries connect the arteries to veins. The arteries deliver the oxygen-rich blood to the capillaries, where the actual exchange of oxygen and carbon dioxide occurs. The capillaries then deliver the waste-rich blood to the veins for transport back to the lungs and heart. Veins carry the blood back to the heart.
Arteries form part of the circulatory system. They carry blood that is oxygenated after it has been pumped from the heart. Arteries also aid the heart in pumping blood. Arteries carry oxygenated blood away from the heart to the tissues, except for pulmonary arteries, which carry blood to the lungs for oxygenation.(Usually veins carry deoxygenated blood to the heart but the pulmonary veins carry oxygenated blood.) There are two unique arteries.rteries (from Greek á¼ÏÏÎ·ÏÎ¯Î± (artÄria) , meaning windpipe, artery) are blood vessels that carry blood away from the heart. While most arteries carry oxygenated blood, there are two exceptions to this, the pulmonary and the umbilical arteries.
