MACROPRESENT ANTIGENSTCELLSmacrophages when they enter the tissue. They are responsible for presenting antigens to the CD4 cell which triggers T cell immunity and the T cell immunity goes on to trigger B cell immunity. Also monocytes release the following cytokines: IL1, IL6, TNFComplementLYSISVASODMAST CELLfunctions include bacterial lysis, vasodilation and increase vascular permeability, triggers mast cell degranulation, chemotaxis and opsonization.KininPAINVASODturned into bradykinin which is responsible for pain, chemotaxis, and increase vascular permeability and vasodilation. Coagulation Cascade FIBRIN MESH TRAPThe ultimate function of this system is to form a fibrin mesh to stop bleeding and to trap microorganisms. b.Analyze the steps of the arachidonic acid pathway. 6.Analyze disorders which affect immune function. c.Identify the etiology, pathophysiology and clinical manifestations of an allergic immune response.
