The second line of defense would try to stop those who try to enter the pores. These salts kill of most of the pathogens that enter the pores. Finally, if the pathogens are still luckily enough to get in, the body excretes a line of mucus. This mucus traps the pathogens. Besides this, the mucus also contains enzymes, which also help destroy the pathogens. Some cells that engulf pathogens are known as phagocytes. This is so because the phagocytes engulf the pathogens through a special process known as phagocytosis. An example of a phagocyte would be blood cells known as leukocytes. The whole job of these leukocytes is to find and engulf disease-causing bacteria. They travel along the bodily fluids to the area of infection. What many people refer to as Pus is actually the left over of dead leukocytes and pathogens. Serious infections cause the swelling of the nymph nodes as there are too many dead leukocytes and pathogens to store for excretion from the body. Antigens are foreign proteins to the human body. In turn, these foreign proteins cause a reaction. Usually, the main cause of these foreign proteins would be toxins from pathogens or microorganisms. When an antigen enters the body, a certain reaction occurs. When it has been found out that an antigen really is present, it causes the spleen and the lymph nodes to produce a substance known as antibody. These antibodies are a specifically designed substance to track down and destroy the antigen. An antitoxin is a kind of antibody. This kind of antibody is specifically used to go after toxin release by these pathogens. Once the antitoxin locates the toxin released by harmful pathogens, the antitoxin would go and destroy it. The general definition of immunity is the ability for an organism to confront pathogens that can cause diseases. Immunity can be acquired by inheriting it. Inherited immunity is with you when you are born and is usually passed down to you by your mother. Another name ...
