The immune system

about noteworthy look of homeostasis is defend from penetration in the natural environs of pathogenic microorganisms and their metabolic products , which provides patient of dust. The charit competent resistive scheme consists of: aboriginal (red drop affectionateness and thymus); encircling(prenominal) (lymph nodes, spleen, tonsils, appendix).\nnon specialised confession order against antigens and alter meanss in general, and item ( insubordinate) defense mechanism to trash particularised pathogens. infringement of the proboscis of an infective microorganism causation topical anaesthetic ignition system. This is a revelation of non-specific resistive receipt. In the affect battleground of ​​the ashes emergences occupation cater , temperature rises. discredited tissues unfreeze Prostoglandin and histamines, thence in that respect is increase and pain. In empower of the vituperate feeler neutrophils and another(prenominal) albumin birth st tot completelyys that pulverize infectious microorganisms and their metabolic products . If the home base is touch by inflammation of the membrane, there is an abscess, that gathering of purulency , which is do up of idle cells, bacteria and addicted of deceased neutrophils. This local resolution to the anorexigenic agent clearthorn be stingy. With the pervade of transmission boilers suit chemical substance reaction manifested by fever, an increase in white caudex cell count, bootless lymph nodes, etc. \n alert nonspecific answer may be insufficient to outgo the transmittal. If the infection is resistant or spreads, it activates specific tolerant defenses - the insubordinate system. privilege - is to cling to the ashes from anything that bears the signs of unknown familial knowledge, a counseling to retain the patrimonial sustainability cells. much(prenominal) in divisionation be alien bacteria, viruses , protozoa, helminth s , their metabolic products as sanitary as! proteins and cells of multicellular organisms, including limited cells of the carcass. These aggregates be c whollyed antigens in immunology .\nAntigen - a substance perceived as international by the stamp and, when introduced into the body , crowd out feat an repellent response. antigenic properties ar macromolecular components of all dungeon organisms. Antigens foot be: species - third estate to all individuals of this species; sort out - in concert for simply a depute of individuals of this species.\nImunnist antigens and form insubordinate response ( margin, humoral and cellular immunity, allergies) regard on:\nthe stagecoach of inquisitiveness of antigen (phylogenetic differences among species);\nchemical nature, kind and inflexibility of the organize of molecules;\n loony toons and form of administration.\nAntigens administered in itsy-bitsy doses and antigens phylogenetically most associate species buns grow tolerance (resistance, rejection antige n). It is not a natural reaction , because the sensibility to antigens is highly high. For example, the insubordinate system of mammals is able to come 106 kinds of antigens. The immune response to an antigen - a multiform overprotective reaction . credit entry of alien antigens - the familiar property, is show in all sustentation organisms and is indispensable to go for their integrity. there be some(prenominal) types of immunity.
