| Neurophils , eosinphils and basiophils are | polymorphnuclear cells |
| Polymorphonuclear neutrophils are | the most numerous cells among WBCs |
| Polymorphonuclear basophils are | the least numerous cells among WBCs |
| Granulocytes survive up to : | 4 – 8 hours in the blood 4-5 days in tissues |
| Monocytes survives up to | 10-20 hours in blood |
| Monocytes swell in the tissues sites and change into | tissue macrophages |
| Lymphocytes survive up to | weeks to months |
| Platelets are replaced within | about 10 days |
| WBCs move through tissue spaces by WBCs move through tissue spaces by | ameboid movement |
| WBC are attracted toward inflamed areas by | chemotaxis |
| WBCs enter the tissue by | diapedesis |
| Phagocytosing cells will eliminate objects that have | rough surfaces, lack of the protective protein coat |
| Monocyte - Macrophage System is also known as: | the reticuloendothelial system |
| Histocytes are | tissue marcophages in the skin and subcutaneous tissue |
| kupffer cells are | marophages in the liver sinsoids |
| The immune system first line of defense against infection | is provided by the tissue macrophages |
| The Immune system second line of defense against infection | is provided by the neutrophil invasion of the infected area |
| The immune system third line of defense against infection | is provided by a second macrophage invasion into the inflamed tissue |
| The fourth line of defense aganist infections | is provided by increasing the production of granulocytes and monocytes of the bone marrow |
| Pus is composed of | dead neutrophils, dead macrophages ncrosed tissue and tissue fluid |
| Eosinphils play a major role in defending the body in: | Parasitic infections and allergic reactions |
| Basophils librate | heparin |
| Leukopenia | is reduced WBCs count |
| Leukocytosis | is increased total number of WBCs |
| Myelogeous Leukemia is a | malignant condition of the bone marrow |
| polymorphnuclear neutrophils consitute | 62% of the WBCs |
| polymorphnuclear esoinophils consitute | 2.3% of the WBCs |
| polymorphnuclear basophils consitute | 0.4% of the WBCs |
| monocytes consitute | 5.3% fo the WBCs |
| Particles phagocytoized by marcophages are digested mostly by | lysosomes |
| "Walling-Off" in inflammation is a result of | blocking the area with fibrinogen clot |
| Acquired immunity depends on | exposure to antigens |
| Lymphocytes are considered | the basis of acquired immunity |
| metastatic growth of abnormal WBCs in abnormal sites occur in | leukemias |
| GM-CSF stimulates the production of | graulocytes and monocytes |
| Histamine is produced by | the mast cells |
| irriation by gamma rays could results in | leukopnia |
| lymphocytic leukemia usually starts in | lymph nodes |
| long standing metabolic starvation results in | death |
| formation of giant cells is a result of | macrophages phagocytozing none digestable particles |
