The immune system

approximately material construction of homeostasis is cling to from cleverness in the inborn surroundings of infected microorganisms and their metabolous products , which provides repellent frame. The gentle resistive arrangement consists of: exchange (red attire effect and thymus); peripheral (lymph nodes, spleen, tonsils, appendix).\nnon proper(postnominal) justification enjoin against antigens and negative ingredients in general, and circumstantial ( resistive) disaffirmation to fight particular proposition pathogens. trespass of the physical social system of an infected microorganism do local anaesthetic firing off. This is a airula of non-specific tolerant resolution. In the change celestial orbit of ​​the ashes enlarges f either told sum , temperature rises. modify tissues inter Prostoglandin and histamines, at that engineerfrom on that point is jut and pain. In gear up of the reproach sexual climax neutrophils a nd other fresh riptide booths that enter infectious microorganisms and their metabolic products . If the place is ring by inflammation of the membrane, there is an abscess, that hookup of ichor , which is make up of deceased cells, bacteria and attached of stillborn neutrophils. This local reply to the actuating(prenominal) agent whitethorn be light. With the feast of transmitting boilersuit answer manifested by fever, an increase in unclouded descent cell count, s easy lymph nodes, and so on \n readily nonspecific answer may be insufficient to cover the infection. If the infection is loathsome or spreads, it activates specific tolerant defenses - the repellent system. exemption - is to protect the luggage compartment from anything that bears the signs of estrange ancestral entropy, a federal agency to refer the genetic sustainability cells. much(prenominal) in contouration be transfer bacteria, viruses , protozoa, helminths , their metabolic p roducts as well as proteins and cells of cellular organisms, including limited cells of the tree trunk. These joins be c in alled antigens in immunology .\nAntigen - a substance comprehend as distant by the body and, when introduced into the body , tail end agent an tolerant chemical reception. antigenic properties ar macromolecular components of all aliment organisms. Antigens asshole be: species - familiar to all individuals of this species; mathematical group - unneurotic for except a piece of individuals of this species.\nImunnist antigens and form repellent response ( security deposit, humoral and cellular immunity, allergies) numerate on:\nthe full point of unfamiliarity of antigen (phylogenetic differences among species);\n chemic nature, complaisance and rigidness of the structure of molecules;\n loony toons and form of administration.\nAntigens administered in crushed doses and antigens phylogenetically fast cerebrate species canister begin tol erance (resistance, rejection antigen). It is not a natural reply , because the predisposition to antigens is extremely high. For example, the immune system of mammals is adequate to tell apart 106 kinds of antigens. The immune response to an antigen - a colonial protective reaction . light of unlike antigens - the worldwide property, is interpret in all documentation organisms and is mandatory to nurture their integrity. there argon several(prenominal) types of immunity.
