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.
Tissue fluid passes out of the space between cells and through the walls of lymph capillaries. ... Like veins in the blood circulatory system, lymph vessels have valves that help push lymph slowly back towards the heart. Eventually the lymph enters a large collecting tube, the thoracic duct, located near the heart.
