The lymph vessels carry lymph from the tissues through the lymph nodes, where lymphocytes neutralize or kill and macrophages consume pathogens, then deliver the cleansed fluid to the blood.he lymphatic capillaries merge into the afferent lymphatics, somewhat larger lymph vessels that carry the lymph among the lymph nodes. The lymphatic capillaries in the SMALL INTESTINE, called lacteals, are uniquely able to absorb the fatty products of digestion, which they ultimately deliver to the blood.
Transportation of the lymph is the most important function of the lymphatic vessels of the lymph nodes. The lymph nodes then act as filters to filter out impurities from the b â¦ lood vessels and produce antibodies. vessel that, unlike a blood vessel, carries fluid only away from tissues. This fluid is a pale, watery substance known as lymph. The smallest lymph vessels are the lymph ca â¦ pillaries, which begin in the tissue spaces as blind-ended sacs.
