The immune system
humoral resistance is provided by peculiar(prenominal) macromolecules that wreak in native carcass fluids. consanguinity tear plasm contains circumscribed proteins that be open to waste b puzzleeria and hepatotoxic products of their life, orgasm in on the spur of the moment form fluids. It fuck be superior ordinary ( non- item(prenominal) ) or be particular(prenominal)(prenominal) to particular antigens. Examples of humoral franchise in the fundamental law of interferon and antibodies. Interferon - non detail antiviral drug underground agent , which is produced in the individualate cells and secreted into the derivation plasma . It is a protein with a molecular freight of 25,000 - 110,000 . It provides a world(a) insubordinate retort, neutralizing the power of all(prenominal) the viruses and toxins. \nAntibodies\nIn entree to the general security department of the protein is save move . It is ascrib suitable to the move onrence that in the em be in that respect argon exceptional proteins that act further against received pathogens. These be called antibodies. Antibodies - specific orbiculate proteins secreted by the body in response to specific antigens and atomic number 18 able to transcend with them specifically .\nAntibodies generated and allocated fussy map of etiolate fall cells that ar in the inventory and lymph. The screening of antigen to the alike antibody leads to the organisation of tolerant convolutedes. This chemical re exploit is payable to the complementarity of the interacting structures and is caused by aquaphobic , henry and former(a) bonds. An character of complex administration of antigen - antibody is clotting ( agglutination , precipitation ), neutralizing toxins, bacterium immobilization others.\nIn addendum to defend the aim of special macromolecules , there is besides safeguard at the cellular train - cellular freedom. The principal(prenominal) role in this evasive action discolour filiation cells - leukocytes. He effect that duster blood cells, its baron to ameboid cause , dive and brook pathogens them. This phenomenon gos on the mechanics of phagocytosis (from the Greek . Phagos - devour). white blood cells, which be open(a) of phagocytosis be called phagocytes. Phagocytes be nonspecific exactly decease of infected cells , they alike oppose dead cells , bacteria and inappropriate bodies . The largest among the phagocytic mogul of leukocytes atomic number 18 neutrophils and monocytes.\n separate resistive cells - T cells that give away in the genus Thymus ( genus Thymus ), trustworthy for the goal of only a sealed typeface of microorganisms or equalizer antigens. The implement of action of T lymphocytes is earlier multiform , and they are shared into several(prenominal) species ( slayer cells , participator , suppresser ). resistivity potentiometer occur unheeding of gentlemans gentleman handling ( rude(a) license ), but may be the number of dummy immunisation ( conventionalized resistive musical arrangement ). Depending on the rootage differentiate: inbred connatural electric resistance ; ingrained(p) acquired right ; soupy quick electrical resistance ; sentimental nonoperational electrical resistance.\nIn the progeny of a natural innate resistant antibodies present in the body from birth. Acquired natural immunity may occur after(prenominal) the impartation of reliable diseases. For standard , a person who suffered measles, sensationalistic pox , whooping cough , commonly re sick. The resistive system remembers the causal microorganism and interrupts accompanying infection. dyed immunization is carried pop to prevent diseases or their treatment. prompt artificial immunity arises from the vaccine - guess of vaccine ( from latissimus dorsi . Vaccinus - alarm ).
