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.
The primary function of the lymph system is to protect the body from infection and disease via the immune response. It does this by production, maintenance and distribution of lymphocytes (infection fighting cells).The lymph system also helps to maintain fluid movement between the cells and the bloodstream.he lymph vessels which absorb, collect and transport lymph throughout the body are equipped with one way valves which propel the lymph in one direction. The lymph fluid is moved by muscle contraction, breathing, arterial pulsations or application of external pressure, such as massage or compression of some sort.
