The lymphatic system is a network of tissues and organs that help rid the body of toxins, waste and other unwanted materials. The primary function of the lymphatic system is to transport lymph, a fluid containing infection-fighting white blood cells, throughout the body.
Lymph enters vessels known as the subclavian veins, which transport it back to the circulatory system. Afferent vessels transport fluid into the lymph nodes, while efferent vessels carry filtered lymph away from the lymph nodes. White blood cells called lymphocytes are a major part of the lymphatic system.Lymph nodes may become swollen when a person gets sick.fter the lymph has been filtered by the lymph nodes, it passes into the efferent vessels. These lymph vessels come together in large groups sometimes referred to as a lymph trunk. They drain the filtered fluid into one of two lymph ducts, which are very large lymphatic vessels.
