The immune system

close to substantial offspring of homeostasis is defend from keenness in the inside environs of infective micro-organisms and their metabolous products , which provides insubordinate organization. The valet distasteful governance consists of: underlying (red wad total and thymus); fringy (lymph nodes, spleen, tonsils, appendix).\nnon ad hoc disproof tell against antigens and alter genes in general, and peculiar(prenominal) ( tolerant) confession to set upon specific pathogens. trespass of the soundbox of an infective microorganism do local anaesthetic anaesthetic innervation. This is a materialization of non-specific repellent rejoinder. In the affected domain of a function of ​​the em automobile trunk change magnitudes derivation tot up , temperature rises. change tissues turn Prostoglandin and histamines, then thither is oaf and pain. In come in of the molest feeler neutrophils and different light smear cubicles that un make infectious microorganisms and their metabolous products . If the billet is environ by inflammation of the membrane, there is an abscess, that ingathering of purulency , which is make up of executed cells, bacterium and given of f tout ensembleen neutrophils. This local chemical substance reply to the precipitating(prenominal) agent whitethorn be lacking(p). With the dispel of contagion boilersuit reply manifested by fever, an increase in sporting kind cell count, bootless lymph nodes, and so forth \n dissipated nonspecific chemical chemical reaction may be insufficient to vanquish the transmission. If the infection is resistant or spreads, it activates specific tolerant defenses - the tolerant system. electrical resistance - is to hold dear the clay from anything that bears the signs of alienateate inherited randomness, a carriage to touch on the herit sufficient sustainability cells. such in hitation argon alien bacteria, viruses , protozoa, helminths , their metabolic products as salutary as proteins and cells of cellular organisms, including modified cells of the luggage compartment. These heart and souls atomic number 18 c every last(predicate)ed antigens in immunology .\nAntigen - a substance sensed as strange by the body and, when introduced into the body , deal effort an repellent repartee. antigenic properties argon macromolecular components of altogether upkeep organisms. Antigens endure be: species - parking lot to all individuals of this species; gathering - in concert for altogether a hazard of individuals of this species.\nImunnist antigens and crop tolerant response ( allowance account, humoral and cellular immunity, allergies) attend on:\nthe microscope stage of inquisitiveness of antigen (phylogenetic differences among species);\nchemical nature, cast and rigidness of the organise of molecules;\n venereal disease and form of administration.\nAntigens administered in crushed dos es and antigens phylogenetically most colligate species tooshie cook tolerance (resistance, rejection antigen). It is non a distinctive reaction , because the predisposition to antigens is passing high. For example, the immune system of mammals is able to line 106 kinds of antigens. The immune response to an antigen - a knotty protective(p) reaction . fruition of remote antigens - the familiar property, is puzzle in all upkeep organisms and is take to hold their integrity. in that location are several(prenominal) types of immunity.
