|+||====== Lymph System: ======|
|+||When sickness or infection invades the body, the immune system is the first line of defense. A big part of that defense is the lymph system.|
|+||[[lymph]] is a transparent fluid containing white blood cells, which help fight [[infection]]. The main types of [[white blood cells]] are [[lymphocytes]]. [[lymph]] is carried through the body by [[lymph vessel]]s that have valves and muscles to help move the fluid. Along the route are lymph nodes that serve as filters for harmful substances. This network of vessels and [[:|lymph nodes]] together is called the lymph system.|
