A&P11-Class Notes Pg 29 Lymphoid Cells & Tissues
| Question | Answer |
|---|---|
| lymphoid cells provide: | defense against invaders such as micro organisms |
| lymphoid cells also help produce inflammatory response for: | defense via action of phagocytes (microphages) |
| Lymphoid cells also provide production of defensive: | chemicals -histamines & antibodies |
| Types of lymphoid cells: 4 | lymphocytes, macrophages, dendritic cells (dendrites), and reticular cells |
| main warriors of the immune system is: | lymphocytes |
| lymphocytes are cells that develop in: | red bone marrow |
| lymphocytes mature to form: | T-cells or B-cells |
| T-cells are: | T-lymphocytes |
| B-cells are: | B-lymphocytes |
| T-cells job is to: | manage immune response & attack/destroy foreign cells |
| B-cells job is to: | protect body against antigens by producing plasma cells that secrete antibodies |
| which L cell help by activating T-cells and also phagocytizing foreigh materials: | Macrophages |
| Dendritice cells (dendrites) are what shape: | spiney shaped cells unique to lymphatic tissues. |
| a cell that is a specialization of the monocyte is: | dendritic cell |
| what produces the reticular fiber stroma of lymphatic organs: | reticular cells |
| fibroblastic cells are also: | reticular cells |
| connective tissues that act as a domain as well as a proliferation site for lymphocytes is: | lymphoid tissues |
| Lymphoid tissues are also a good observation station for: | phogocytes |
| Lymphoid tissues include several types of: | reticular connective tissue |
| Lymphoid tissues dominate all lymphoid organs except: | thymus |
| lymphocytes lurk in: | spaces of the reticulum |
| hang on the framework refers to: | microphages |
| types of lymphoid tisses is: 2 | diffuse & lymphatic nodules (follicles) |
| Diffuse lymphoid tissue consists of: | scattered reticular elements |
| diffuse L tissue is found in all: | body tissues |
| Diffuse L tissue is more prevalent in: | mucous membranes & L organs |
| Lymphatic nodules (follicles) are productioon areas where: | B cells produce plasma cells |
| L nodules are located within: | larger L organs |
| tightly packed spherical structures refers to | lymphatic nodules |
| Germinal centers are: | the areas of the L. nodules that stain lighter than other areas. |
| L follicles (nodules) are also present as: | isolated masses in both the intestinal wall and the appendix. |
| Peyers patches is: | nodules in the intestinal wall |
