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.
This fluid becomes the interstitial fluid that surrounds cells. Lymph vessels collect and filter this fluid before directing it toward blood vessels near the heart. It is here that lymph re-enters blood circulation. Returning lymph to the blood helps to maintain normal blood volume and pressure.It also prevents edema, the excess accumulation of fluid around tissues. Large lymphatic vessels are composed of three layers.nce the fluid enters the lymph capillaries, it is called lymph. Lymph capillaries can be found in most areas of the body with the exceptions of the central nervous system, bone marrow, and non-vascular tissue. Lymphatic capillaries join to form lymphatic vessels. Lymphatic vessels transport lymph to lymph nodes.
