Terms | Definitions |
|---|---|
 Lymphocytes | primary cell for immune response; originates in liver spleen and bone marrow |
| T-lymphocytes | mighrate through Thymus to become cell mediated immunity "T" lymphcytes |
| B-lymphocytes | mature in "B"one Marrow |
| Lymph nodes | filter lymph and phagocytes (eat foreing particles) from harmful bacteria and microorganisms |
| Platelets | important role in coagulation |
| erythrocytes | transport respiratory gases, depend on hemoglobin. |
| Low Hemoglobin in which diseases | MM, hodgkins lymphoma, leukemia |
| Leukocytes | most important cellular compenent in body's defenses |
| 3 types of granulocytes | neutrophils, basophils, eosinophils |
| neutrophils | cellular defense phagocytosis of small pathogenic microorganisms, bacterial infections, inflammation and stress responses: NOT VIRUSES (neutro = not virus), BACTERIAL INFECTIONS |
| eosinophils | lining in respiratory and digestive tract, PARASITES (eewww!!!) and allergens |
| basophils | contain histamines (anti inflammatory heparin (anti coagulant) ALLERGIES AND HISTAMINE REACTION (think BEE STING) |
| Agranulocytes | Lyphocytes adn Monocytes |
| lymphocytes | smalles, T's directly attack infected or canceruos cells, VIRAL infections |
| monocytes | largest T, phagocytosis of large bacterial organisms, CHRONIC VIRAL infections too |
| Mentzer index | MCV/RBC |
| Mentzer index: thalassemia | Ratio MCV/RBC < 13 |
| Mentzer index: hemoglobinopathy, iron def anemia | Ration MCV/RBC > 13 |
| Thalassemia | genetic disfunction with alpha or beta globin proteins, rbc doesn't hold adequate hemoglobin d/t shape. PX is tired,etc |
| Hemoglobinopathy | sickle cell anemia is one form, issue with genetic chain in cell that doesn't allow hemoglobin to be adequate |
| MCV | Mean corpuscular value - size of the blood cell - ex MACRO or MICRO |
| Blood Types | A, B, AB, O |
| Percentage of formed elements in blood | 45% |
| percentage of plasma in blood | 55% |
