What is the function of lymphatic vessels?

Lymphatic vessels return excess interstitial fluid to the bloodstream, carrying lymph from peripheral tissues toward the venous system. As lymph travels through increasingly large vessels, it passes through lymph nodes that screen for pathogens and help coordinate immune responses. Eventually it drains into the venous circulation via the thoracic duct or the right lymphatic duct at the junctions of the internal jugular and subclavian veins. The vessels rely on valves and surrounding muscle movement to propel lymph forward. This function is distinct from oxygen transport by blood and from antibody production, which occurs in immune cells within lymphoid tissues; the vessels themselves do not produce antibodies.
