0the component of the lymphatic system is the lymph nodes
Afferent lymphatic vessels
Lymph capillaries
Lymph is a fluid. It flows through the lymphatic vessels by one way valves which allows lymph move way through lymphatic system. Subclavian suction, and skeletal muscle pumps help to propel the lymph through the lymphatic vessels.
collecting vessels
The sequence of fluid flow is blood capillaries.... interstitial space or interstitial fluid..... lymphatic capillaries.... lymphatic vessels.... lymphatic ducts..... junction of the internal jugular and subclavian veins. Then what helps this whole sequence is the skeletal muscle pump and the respiratory pump.
The lymphatic system includes organs and cells that filter lymph and blood and destroy foreign microorganisms. Lymph leaks out of capillaries to bathe body cells and circulates among tissue cells and the heart. Organs of the lymphatic system contain lymphatic tissue, Lymphocytes, a few other cell types, and connective tissue.
