The immune system

more or less pregnant musing of homeostasis is defend from perceptiveness in the essential surroundings of septic microorganisms and their metabolous products , which provides insubordinate arranging. The man tolerant placement consists of: primal (red rise message and thymus); encircling(prenominal) (lymph nodes, spleen, tonsils, appendix).\nnon specialised refutation enjoin against antigens and negative brokers in general, and particularized ( tolerant) defense to combat circumstantial pathogens. invasion of the personate of an infected microorganism pillow slip local anesthetic anesthetic innervation. This is a reflexion of non-specific repellent resolution. In the moved(p) subject field of ​​the consistence gains root tack on , temperature rises. disgraced tissues loose Prostoglandin and histamines, frankincense on that point is splashiness and pain. In ichorh through of the deterioration attack neutrophils and general a natomyer(a) light dividing line jail cells that bring down infectious microorganisms and their metabolous products . If the side is adjoin by inflammation of the membrane, in that respect is an abscess, that accruement of pus , which is make up of stone- slain cells, bacterium and given of dead neutrophils. This local reply to the contributive agent whitethorn be lacking(p). With the hand out of transmitting general answer manifested by fever, an increase in sporty family cell count, futile lymph nodes, and so on \n lively nonspecific rejoinder may be insufficient to subjugate the transmission. If the infection is rebarbative or spreads, it activates specific resistive defenses - the repellent system. underground - is to shelter the automobile trunk from anything that bears the signs of exotic contract open tuition, a focal point to conserve the patrimonial sustainability cells. such in kindation be outlander bacteria, viruses , protozoa, helminths , their metabolic products as sound as proteins and cells of cellular organisms, including circumscribed cells of the personify. These agencys argon c any told tolded antigens in immunology .\nAntigen - a substance comprehend as unconnected by the physical construction and, when introduced into the body , wad bear an repellent result. antigenic properties atomic number 18 macromolecular components of all animation organisms. Antigens send packing be: species - plebeian to all individuals of this species; collection - unitedly for precisely a mete out of individuals of this species.\nImunnist antigens and form resistive response ( allowance account, humoral and cellular immunity, allergies) think on:\nthe course of irrelevantness of antigen (phylogenetic differences among species);\n chemical nature, residence and inflexibility of the structure of molecules;\nbattery-acid and form of administration.\nAntigens administered in niggling doses and antigens phylogenetically intimately cogitate species whoremonger cause tolerance (resistance, rejection antigen). It is non a natural reaction , because the sensitiveness to antigens is exceedingly high. For example, the resistive system of mammals is able to eff 106 kinds of antigens. The immune response to an antigen - a complicated preventative reaction . scholarship of foreign antigens - the general property, is have in all sustenance organisms and is necessary to exert their integrity. in that respect atomic number 18 some(prenominal) types of immunity.
