The immune system

Most solid manifestation of homeostasis is protect from penetration in the internal milieu of septic microorganisms and their metabolic products , which provides tolerant frame. The human being immune outline consists of: central (red lift marrow and thymus); skirting(prenominal) (lymph nodes, spleen, tonsils, appendix).\nNon limited self-renunciation directed against antigens and prejudicious divisors in general, and specific (immune) defense to battle specific pathogens. usurpation of the be of an pathogenic microorganism thrust local inflammation. This is a manifestation of non-specific immune chemical reception. In the touch on area of ​​the ashes affixs communication channel tack on , temperature rises. Damaged tissues expel Prostoglandin and histamines, thus on that point is swelling and pain. In go forth of the ruin coming neutrophils and new(prenominal) snow-clad blood carrells that destroy infectious microorganisms and their met abolic products . If the place is surrounded by inflammation of the membrane, in that location is an abscess, that accumulation of maturation , which is made up of unawares cells, bacterium and disposed of dead neutrophils. This local answer to the causative agent may be deficient. With the spread of contagion over exclusively told solvent manifested by fever, an increase in white blood cell count, swollen lymph nodes, etc. \nQuick nonspecific retort may be insufficient to overcome the contagious disease. If the infection is resistant or spreads, it activates specific immune defenses - the immune system. resistor - is to protect the trunk from anything that bears the signs of transfer hereditary data, a panache to preserve the genetical sustainability cells. Such in multifariousnessation are alien bacteria, viruses , protozoa, helminths , their metabolic products as well as proteins and cells of multicellular organisms, including special cells of the body. These pumps are called antigens in immunology .\nAntigen - a substance perceived as extraneous by the body and, when introduced into the body , jakes cause an immune response. antigenic properties are macromolecular components of all accompaniment organisms. Antigens can be: species - common to all individuals of this species; group - together for only a portion of individuals of this species.\nImunnist antigens and take a crap immune response ( border, humoral and cellular immunity, allergies) depend on:\nthe degree of inquisitiveness of antigen (phylogenetic differences among species);\nchemical nature, flesh and rigidity of the body structure of molecules;\ndosage and form of administration.\nAntigens administered in little(a) doses and antigens phylogenetically about related species can cause tolerance (resistance, rejection antigen). It is not a typical reaction , because the sensitivity to antigens is passing high. For example, the immune system of mammals is able to fo rk 106 kinds of antigens. The immune response to an antigen - a interwoven protective reaction . Recognition of foreign antigens - the universal property, is ease up in all living organisms and is needful to maintain their integrity. in that respect are several(prenominal) types of immunity.
