| innate immunity | inborn immunity |
| acquired immunity | gained immunity during lifetime |
| 2 types of immunity | innate and acquired |
| 2 types of acquired immunity | active immunity and passive immunity |
| active immunity | antibodies that develop to fight antigens after we are born |
| passive immunity | antibodies by other animals are introduced into the human bloodstream |
| 2 types of active immunity | naturally acquired, and induced active immunity |
| naturally acquired immunity | immunity gained from exposure to antigens (colds, chicken pox) |
| induced active immunity | antigens introduced to the body to produce antibodies (vaccinations) |
| 2 types of passive immunity | natural passive immunity, and artificial passive immunity |
| natural passive immunity | immunity acquired from maternal transfer (placenta or breast milk) |
| artificial passive immunity | antibodies introduced directly into bloodstream (immunoglobulin shot) |
| T-Cells | produced by the thymus; part of naturally acquired immunity |
| B-Cells | produced by the bone; part of naturally acquired immunity |
| Lymphatic system | responsible for the transportation of white blood cells |
| Swollen lymph nodes | body is busy fighting off infection |
| Allergy | overabundance of an antigen to which the immune system responds |
| Cell-mediated immunity | T-Cell activation or memory T-Cell activation; required before antibody-mediated immunity |
| Antibody-mediated immunity | B-Cell or memory B-Cell activation |
