<P> Rhythmic contraction of the vessel walls through movements may also help draw fluid into the smallest lymphatic vessels , capillaries . If tissue fluid builds up the tissue will swell ; this is called edema . As the circular path through the body 's system continues , the fluid is then transported to progressively larger lymphatic vessels culminating in the right lymphatic duct ( for lymph from the right upper body ) and the thoracic duct ( for the rest of the body ) ; both ducts drain into the circulatory system at the right and left subclavian veins . The system collaborates with white blood cells in lymph nodes to protect the body from being infected by cancer cells , fungi , viruses or bacteria . This is known as a secondary circulatory system . </P>
