The immune system is made up of different parts that are constantly protecting the body from disease-causing microorganisms known as pathogens. By keeping out these infectious pathogens out of the body or destroying the pathogens that do enter the body, the immune system is a complex network of cells and organs that protect the body from infection.
The primary immune response is the response that is activated when the body is first exposed to an antigen, resulting in the activation of lymphocytes. If the human body is encounters the same antigen again, the secondary immune response is activated. Started by memory B cells, the secondary immune response is faster than the primary immune response and responds with a greater magnitude and production …show more content…
It is made of about 20-30 proteins which have a variety of function, but they enhance immune response.
- The cells of the complement system are synthesized continuously by the cells of the liver and macrophages. These complement proteins bind to the surfaces of microorganism, specifically the ones that are already tagged by antibodies. Thus, they serve as a marker to indicate the presence of a pathogen to phagocytic cells (macrophages and B cells). Furthermore, through a process of opsonization, complement proteins enhance engulfment. During opsonization, certain proteins come together to destroy pathogens by causing their contents to leak.
A local inflammatory response can also be triggered when tissue is damaged by physical injury or pathogens entering the body. This leads to a release of several chemical signal. One of the chemical signals is known as histamines. Histamines are released by mast cells in response injury. The function of histamines is to trigger the dilation and permeability of nearby capillaries. As a result, this helps get clotting agents and/or phagocytic cells to the injured area. The inflammatory response, with cytokines, increase the core body temperature, which results in a fever. They also cause the symptoms of feeling sick (lethargy, muscle pain, and
