lymphatic System

Lymphatic system and Immunity (Martini)

genetically determined; It is present at birth and has no relationship to previous exposure to the antigen involved. Innate Immunity
Is not present at birth; you acquire immunity to a specific antigen only when you have been exposed to that antigen (can be active or passive). Acquired Immunity
prevent the approach, deny the entry or limit the spread of microorganisms or other environmental hazards. Nonspecific Defenses
1) Physical barriers (hair & skin)2) Phagocytes3) Immunological surveillance4)Interferons5) Complement6) Inflammatory response7) Fever 7 Non specific Defenses
Immunity which is provided by the coordinated activites of T cells and B cells, which respond to the presence of specific antigens. T cells = cell mediated immunity (cellular immunity). B cells = antibody-mediated immunity (humoral immunity)*body fluid. Specific Defenses
specificity, versatility, memory, and tolerance. Memory cells enable the immune system to "remember" previous target antigens. Tolerance is the ability of the immunesystem to ignore some antigens, such as normal self. Immunity properties
slow the spread of a virus by making the synthesizing cell and its neighbors resistant to viral infections. Interferons
the ability to produce an immune response after exposure to an antigen. Immunological competence
