The body has natural defence mechanisms against microbes that invade it. The first line of defence is the body's largest organ the . If holes are formed, then from within the blood help the blood to at the site of the wound. Microbes can enter through the other orifices of the body. Body cavitives are lined with mucous membranes which produce which traps microbes and also contains chemicals to kill them. The gastric juice (mainly ) in the stomach will kill most bacteria that get that far and all fungi and viruses. If there are numbers of bacteria the gastric juices will not kill them all. If the body becomes infected then it can remove large numbers of microbes through physical means. Coughing and remove microbes from respiratory tract and diarrhea remove pathogens and toxins in the gastrointestinal tract. Fluids such as urine, , saliva, , and blood from injured blood vessels also flush microbes from the body. Should the pathogens enter the blood stream, blood cells destroy them through the process of . Pathagens are engulfed and then digested by the blood cell. Pathogens cause damage to the body because they produce (a natural poison). The body must first stop the production of these toxins (kill the pathogens) and then organs such as the liver can process and break down the toxins.
