Immune System - AP Biology Flashcards
Terms : Hide Images [1]
| 9046996615 | Inflammatory Response | Vasodilation, phagocytosis, and increase in body temperature |  | 0 |
| 9046996616 | Histamines | chemical signals that trigger vasodilation, increasing blood supply to area and cause inflammation. | 1 | |
| 9046996617 | Phagocytes | White blood cells that engulf invading pathogens e.g., neutrophils, macrophages | 2 | |
| 9046996618 | Chemokines | chemical signals secreted by blood vessel cells that attract more white blood cells (phagocytes) to the area | 3 | |
| 9046996619 | Specific immunity | B and T cells; humoral and cell-mediated response | 4 | |
| 9046996620 | Lymphocyte | White blood cell |  | 5 |
| 9046996621 | B Cells | Humoral response by producing antibodies; activated by T cells or free antigens | 6 | |
| 9046996622 | T Cells | Cell-mediated response, stimulating by APCs (antigen presenting cells) | 7 | |
| 9046996623 | Helper T Cell | Set off an alarm to the immune system that pathogens have broken through the body's line of defense; binds to class II MHC |  | 8 |
| 9046996624 | Cytotoxic T Cell | Kills body cells that have been infected with pathogens; stimulated by antigens and helper T-cells |  | 9 |
| 9046996625 | Macrophages | APC that engulfs large numbers of pathogens; presents antigen to activate T cells |  | 10 |
| 9046996630 | Memory Cells | Responsible for lifelong immunity by storing copy B and T cells to more quickly fight secondary infection |  | 11 |
| 9046996631 | Antibody | Y-shaped protein with variable antigen bind region; slows pathogens to facilitate destruction |  | 12 |
| 9046996632 | Antigen | Identifying marker on the outside of a pathogen |  | 13 |
| 9046996633 | Passive Immunity | Temporary immunity where antibodies are transferred from another animal ex: mother transfers some of her antibodies to her nursing child | 14 | |
| 9046996634 | HIV | A retrovirus that attacks helper T cells |  | 15 |
| 9046996635 | Autoimmune disease | A mistake in the immune system where the body does not properly distinguish self from nonself | 16 | |
| 9046996636 | Allergy | Hypersensitive immune response to certain substances that causes that release of histamine | 17 | |
| 9046996637 | Dendritic Cells | During primary immune responses, the principle antigen-presenting cells in the lymph nodes | 18 | |
| 9046996638 | Innate Immunity | General, non-specific protection to the body, including the skin (barrier), gastric acid, phagocytes, and lysozyme. | 19 | |
| 9046996640 | Natural Killer Cells | A type of white blood cell that can kill tumor cells and virus-infected cells; an important component of innate immunity. | 20 | |
| 9046996641 | Mast Cells | Cells that release chemicals (such as histamine) that promote inflammation. | 21 | |
| 9046996642 | Humoral Response | The branch of acquired immunity that involves the activation of B cells and that leads to the production of antibodies, which defend against bacteria and viruses in body fluids. | 22 | |
| 9046996643 | Cell-mediated Response | The branch of acquired immunity that involves the activation of cytotoxic T cells, which defend against infected cells. | 23 |
