| 5872575481 | Infectious disease | A disease caused by the presence of a living thing in the body. |  | 1 |
| 5872575482 | Toxin | A poison introduced by bacterial pathods that damages cells. |  | 2 |
| 5872575483 | Inflammatory response | Part of the body's defense against pathogens in which fluid and white blood cells leak from the blood vessels into tissues and destroy pathogens by breaking them down. |  | 3 |
| 5872575484 | Phagocyte | A white blood cell that destroys pathogens by engulfing them and breaking them down. |  | 4 |
| 5872575485 | Immune response | Part of the body's defense against pathogens in which cells of the immune system react to each kind of pathogen with a defense targeted specifically at that pathogen. |  | 5 |
| 5872575486 | Lymphocyte | White blood cell that distinguishes between each type of pathogen. |  | 6 |
| 5872575487 | T cell | A lymphocyte that identifies pathogens and distinguishes one pathogen from another. |  | 7 |
| 5872575488 | Antigen | A molecule that the immune system recognizes either as part of the body or as coming from outside the body. |  | 8 |
| 5872575489 | B cell | A lymphocyte that produces proteins that help destroy pathogens. |  | 9 |
| 5872575490 | Antibody | A protein produced by a B cell of the immune system that destroys pathogens. |  | 10 |
| 5872575491 | AIDS | Acquired immunodeficiency syndrome. A disease caused by a virus that attaks the immune system. |  | 11 |
| 5872575492 | HIV | Human immunodeficiency virus. The virus that causes AIDS. |  | 12 |
| 5872575493 | Immunity | The body's ability to destroy pathogens before they can cause disease. |  | 13 |
| 5872575494 | Active immunity | Immunity that occurs when a person's own immune system produces antibodies in response to the presence of a pathogen. |  | 14 |
| 5872575495 | Vaccination | The process by which harmless antigens are deliberately introduced into a person's body to produce active immunity; also called immunization. |  | 15 |
| 5872575496 | Vaccine | A substance used in a vaccination that consists of pathogens that have been weakened or killed but can still trigger the immune system into action. |  | 16 |
| 5872575497 | Antibiotic | A chemical that kills bacteria or slows their growth without harming body cells. |  | 17 |
| 5872575498 | Passive immunity | Immunity in which antibodies are given to a person rather than produced within the person's own body. |  | 18 |
