LYMPHATIC SYSTEM

INTRODUCTION• lymphatic system is part of

the circulatory system and a vital part of the immune system, comprising a network of lymphatic vessels that carry a clear fluid called lymph directionally towards the heart.

•One of the main functions of the lymph system is to provide an accessory return route to the blood for the surplus three litres.

•Main function of the lymphatic system is defensive action.

• Lymph is very similar to blood plasma: it contains lymphocytes and other white blood cells.

FUNCTIONS•It is responsible for the removal

of interstitial fluid from tissues•It transports white blood cells to and from

the lymph nodes into the bones•The lymph transports antigen-presenting

cells, such as dendritic cells, to the lymph nodes where an immune response is stimulated.

CLINICAL SIGNIFICANCE•Lymphadenopathy•Lymphedema•Cancer•Lymphangitis•Kikuchi disease•Chylothorax

•Phlebitis or venitis is the inflammation of a vein, usually in the legs. It most commonly occurs in superficial veins. Phlebitis often occurs in conjunction with thrombosis and is then called thrombophlebitis or superficial thrombophlebitis.

•Thrombosis  is the formation of a blood clot inside a blood vessel, obstructing the flow of blood through the circulatory system.

•Gangrene  is a type of necrosis caused by a critically insufficient blood supply.
