Lymphatic
| Question | Answer |
|---|---|
| Composed of… | Tonsils, Spleen, Thymus, Numerous Glands/nodes, Vessels, Cells that provide body with immunity |
| Interstitial Fluid | Fluid that is found in between cells; Very similar make up of plasma |
| What do they do? | Major site for B & T-cell Lymphocytes (remember the guys that make antibodies??) Responsible for filtration of lymphatic fluid (similar to plasma but lower in protein) |
| Tonsils | Made up of lymphoid tissue Located in back of throat First line of immunity in throat |
| Tonsillitis | disease of tonsils |
| Tonsillectomy | removal of |
| Splenectomy | removal of spleen |
| Edema | Excessive accumulation of interstitial fluid |
| Signs of inflammation: | -Erythema (reddening of skin) -Heat due to increased blood flow and cellular activity -Edema to cushion and dilute toxin - Algesia (pain) -Decreased use and guarding of the injured area |
| What is an antigen? | Any foreign molecule that is capable of stimulating an immune response |
| What does the body do with an antigen? | First Responders…your innate immune response Neutrophils & Macrophages phagocytize the antigen (eat it up!) Fragments of that antigen are moved to the surface of the cell and stimulates the activity of other immune cells |
| Humoral response (immunity through antibody production) | antigen kicks in to create an army |
| T-Lymphocytes (T-cells) | Specialize in various aspects of immune response |
| B-Lymphocytes (B-cells) | Mature in bone marrow, once mature has specialized protein receptors on its surface All are UNIQUE & will bind to a PARTICULAR antigen Once it finds the antigen it matches it will stimulate the humoral response and start making clones to make an army!!! |
