Introduction:

For all living organisms, there is a challenge for surviving by defeating the entire pathogenic organism. The human body kills the pathogen or eliminates the foreign particles by an organized system called the lymphatic system. The lymphatic system or immune system consists of a group of cells or immune cells, which inhabit all the organs of the body. The lymphatic system includes lymphatic organs and a group of lymphatic tissues that are involved in the immune system.
