| Question | Answer |
|---|---|
| Globin chains of normal hemoglobin – | HbA - alpha2 beta 2 |
| Lymphoid system is the precursor for – | T B and NK |
| Secondary or Specific – Dawning of neutrophilia – appear first at - | the myleocyte stage |
| Absolute/Relative study these and know how to figure them! – | relative is percent absolute is multiplied out |
| Normal secquence of cell development – | liver/spleen, thymus, medullary |
| In a wright stain a reticulocyte will have a blue appearance, this is refered to as – | polychromatophilia or polychromatic |
| Term for earliest hematopoietic cells is – | pluripotential stem cell |
| Struction of oxyhemoglobin is – | R structure |
| Structure of a reticulocyte – | non-nucleated with RNA |
| Elevation of Lymphocyte above 40 PERCENT – | relative lyphocytosis |
| Perform Phagocytosis – | Granulocytes, monocytes |
| In order for hemoglobin to combine reversibly with oxygen, iron must be in the - | ferrous state |
| Granulocytes adhearing to the vascular endotheilium - | marginateing pool (the rest are free circulating) |
| Hemoglobin types in Embryonic development – | epsilon and zeta |
| Hemoglobin with higher affinity for O2, accounts for 50-85% of Hgb at birth – | HbF |
| Name of the nucleated RBC just before it loses it’s nucleus is – | metarubricyte |
| Reasons for Lab tests – | establish or rule out diagnosis, confirm a Dr impression, screen for asymptomatic/unknown |
| The presence of nucleoli is associated with - | immature cells |
| Hematopoiesis outside the bone marrow in times of excessive loss of blood – | extramedullary |
| In adulthood the main site of hematopoiesis is in the – | axial skeleton, flat bones, proximal long bones |
| Cellular structure that differentiates promyleocyte from myleocyte – | presence of primary granules in promyleocyte and specific in myleocyte |
| Normal hemoglobin consists of - | 2 alpha and 2 beta |
| protein that grabs it up in extravascular destruction | Haptoglobin – |
| In a normal adult the spleen acts as a site for | – removal of imperfect and aging cells |
| Primary granules first appear in – | promyelocytes |
| polymorphnucleus, small pink red granules in cytoplasm | Segmented neutrophils – |
| Dark blue /black granules in cytoplasm 0-1% leukocytes | Basophil – |
| skyblue cytoplasm 25-35% of normal adult leukocytes and form E, C, U or S shaped nucleus | Lyphocytes – |
| large orange/red granules, | Eosinohil – |
| Complete blood count on a patient reveals the following: White count 28 what is the absolute lymphocyte count (lymph .15) – | 4.2 |
| The granulocytic mitotic pool contains – | myleoblasts thru the myleocyte stage |
| Eosinophils primary function is – | to protect the host from helmith parasites |
