| Questão | Responda |
| The Inflammatory response: | is a cascade of cells that cells that are involved |
| Cells involved in inflammatory response: | Lymphocytes: T-lymphocytes & B-lymphocytes, Antigen |
| Acquired immunity | You were not born with it, & it is not automatic |
| Antigen exposure stimulates... | acquired immunity |
| Lymphocytes are stimulated by... | antigen |
| Antigen stimulates... | Lymphocyte activity, usually protein or parts of proteins |
| T-lymphocytes | cell based immunity |
| B-lymphocytes | Antibody based immunity |
| T-lymphocytes start... | The process of the antigen stimulation of lymphocytes |
| How are T-cells activated? | By antigen receptor match (APC) |
| Occurs in the lymph-nodes or spleen | a. Cytotoxic -activity promoted by cytokines, make holes in virally infected or cancer cells. b. helper-release cytokines promoting clonal expansion of B-cells c. Memory T-cells |
| Types of inflammatory response: | 1. Acute inflammatory response 2. Chronic inflammatory response |
| When __ inflammatory response is not s not sufficient to deal with a pathogen, __ takes over | Acute; Chronic |
| What cells mediate chronic inflammation? | B-cells & T-cells leukocytes/lymphocytes |
| These white blood cells make up the Adaptive Immune System: | B-cells and T-cells |
| Antigen | is the specific structural sequence the receptor can bind to. |
| Where do antigens come from? | from bacteria, not from the body |
| Clonal expansion | copies of the matched T-cell to fight the antigen |
| How are left over T-cells discarded? | They are not, they remain in the body as memory cells. Some even get used up |
| T/F: T-cells can target a damaged d or broken cell(s) and even destroy them. | True |
| Types of T-cells: | 1. Cytotoxic- cell destroyer 2. Helper (t-cells) - help stimulates copies of themselves 3. Memory cells |
| Cytokinesis | - Promote clonal expansion substances released by white blood cells. - differentiate into plasma which release anti bodies |
| Macrophages | present the antigens to T-cells to be destroyed |
| B-cells |
