Immunology - Coursework ExampleInnate immunity is usually immediate and non-specific answer. The Adaptive immune rejoinder is only activated when the pathogen evades the innate immunity. Adaptive immune result acts by recognition of the pathogen and retained after the pathogenic infection has been eliminated (Doan, 2008).The Humoral immune response is a branch of adaptive immune response. Humoral immune response act on pathogens that atomic number 18 outside the bed such as toxins and bacterias, during the response antibodies which are protein bodies nowadays in the body are produced and secreted into the blood stream and other body fluids to help in fighting with the intruding agents by back to them and destroying them (Doan, 2008).In the case of the schoolchild who was first exposed to the avian flu the humoral system retained the response given first hence when the student was infected again by the flu the immune response had the memory and hence acted on it faster than the first time (Doan, 2008).The T helper cells are responsible for suppressing and regulation of the innate responses. Low helper T cells results in hypersensitivity reactions to the patient because the body will view the hosts antigen presenting the antibody as distant and go on to destroy all the host antigens.They include chemical, mechanical, and biological barriers. Chemically the skin produces an antimicrobial agent that protects against pathogens. Mechanically, sneezing helps to expel foreign bodies present in the respiratory tract.This response comes first after an infection. Cytokines are produced and they communicate with the white blood cells to recruit immune cells to the infection site hence better takes place after removal of the pathogens (Doan,
