  2. 2. <ul><li>“ The lymphatic system is a network of very small vessels . It is used as an extensive drainage network. This drainage network helps to keep bodily fluid level in balance. This drainage network also defends the body against infections that are or will happen. The lymphatic system also helps defend the body against germs like viruses, bacteria, and fungi that can cause sicknesses. Those germs are cleansed out in the lymph nodes.” </li></ul><ul><li>Lymphaticsystem – </li></ul>

It detects a </li></ul><ul><li>wide variety of agents, from viruses to parasitic worms, and </li></ul><ul><li>needs to distinguish them from the organism's own healthy </li></ul><ul><li>cells and tissues in order to function properly . ” </li></ul><ul><li>Immune System – Wikipedia, the free encyclopedia </li></ul>
