| Question |
Answer |
| 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 |
