Benefits of fever (pyrexia) and why the body’s defenses may be compromised by antipyretic drugs; sources of pyrogens and how they trigger the onset of fever; the stages and course of a fever and how it combats pathogens; and the danger of excessive fever
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.
