The immune system defends our body from any infection that evades. Organs, tissues, cells, and cell products act together and respond to harmful organisms. and substances that could enter the body. There are three types of response systems in the body:
-The anatomic response: It physically prevents threatening substances from entering your body. Examples of it are the mucous membranes and the skin.The response of this response goes on attack if inflammatory actions goes on.
-The inflammatory system: It works by excreting the invaders from your body. Examples are runny noses, sneezing, fever, coughing, wheezing, and flu are examples of inflammatory system at work. Even if you feel cruddy, the inflammatory system is fighting the illness.
-The immune system: If the inflammatory system fails. The immune system takes action.The response is the central part of the entire immune system. It is made of white blood cell, which fight infections by gobbling up antigens(a virus.) There are two kinds of white blood cells. One of them is called the macrophages, which uses tentacle-like arms to destroy bacteria. Another kind is called the neutrophil, which leaves the blood vessel and travels to the injured site to repair it. About a quarter of white blood cell, called lymphocyte, migrate to the lymph nodes and produce antibodies, which fights disease. |
