Lymphatic capillaries form a mesh-like network of tiny tubes that are distributed throughout the tissue spaces and are located just under the skin.  Unlike blood, which flows throughout the body in a continue loop, lymph flows in only one direction within its own lymphatic system. There are valves within the capillaries ensuring that the flow of lymph is away from the tissues. Lymph flow is unidirectional from the tissues through lymphatic vessels, eventually dumping lymph into the venacava.
