The lymph system is an important part of normal human functioning.  It is responsible for transporting white blood cells and absorbing fatty acids from the intestine.  Similar to the vascular system, it carries nutrients throughout the body and helps to remove waste.  It does however contrast blood flow in one glaring way.  The lymph nodes don’t have a motor that triggers flow.  Lymphatic fluid isn’t pushed through the system by a central engine such as the heart.  On the contrary, it is bodily movements and muscular contractions that help ensure lymphatic fluid circulation.  So be sure to stay active to keep your lymphatic system in order.
