Question | Answer |
---|---|
The process of red bone marrow producing red blood cells | hemapoiesis |
all types of blood cells originate from what type of immature cell found in the marrow? | STEM CELL |
a hormone secreted by the kidneys which helps to stimulate RBC production | ERYTHROPOIETIN |
Medication that stimulates RBC production. Acts just like erythropoietin | EPOGEN $$$ PROCRIT |
What two things make up hemoglobin (HgB)? | HEME - GLOBIN |
What is an immature RBC | reticulocyte |
Destruction of RBC's, results in increased bilirubin | HEMOLYSIS |
If the body were destroying alot of RBC's then you will see an increase in what? | reticulocytes |
Excess of bilirubin in excess of what can be excreted by the liver would lead to what condition? | Jaundice |
the process of digesting unwanted organisms | phagocytosis |
name the granulocytes? GREAT NEW EASY BAKE oven! | Neutrophils - eosinophils - basophils |
WBC'S are leukocytes made up of what 3 things? --- TAG ! you're it! --- | granulocytes - used for phagocytosisagranulocytes - immune responsethrombocytes - clotting process |
Involved in the immune response and include B-cells and T-cells | lymphocytes |
what 2 things performs phagocytosis and facilitates immune response | granulocytes - monocytes |
another name for platelets that initiate the clotting process | thrombocytes |
What organ would "phagocytize" old RBC's (ingest and destroy) - Also resuses iron by sending it to the marrow for re-use - also used for storage for RBCs and platelets | spleen |
where would iron be recycled? | macrophages |
carries fluid form interstitial spaces to and from blood. PREVENTS EDEMA drains into the subclavian vein | Lymph system |
clumps of tissue whos primary function is filtration of pathogens and removal of forgein particles | Lymph nodes |
Acts as a filter - produces several clotting factors - stores Iron | Liver |
What test assesses all 3 types of blood cells formed in the marrow? WBC - RBC - platelets | CBC - complete blood count |
What condition occurs when all 3 major types of blood cells are DEPRESSED (low counts WBC - RBC - platelets) | pancytopenia |
What test measures the gas carrying capacity of the RBC | HgB |
what test tests the volume of RBC's as a percentage of total blood volume | HcT |
abnormally small RBC's | microcytosis (low MCV) |
abnormally large RBC's | macrocytosis (high MCV) |
amount saturation HgB in RBC's | MCHC |
low MCH or high MCH is the | weight of the RBC's |
shape and appearance of RBC's | RBC MORPHOLOGY |
leukocytosis | count over 11,000/ul associated with infection, inflammation, tissue injury/death, or malignancies |
leukopenia | count less than 4,000/ul associated with bone marrow depression |
measures the percentage of each type of leukocyte | WBC differential count |
The actual WBC count is normal BUT there is an increase in neutrophils indicating | infection (bacterial) |
Normal platelet count | 150,000 - 400,000/ul |
platelet count of over 400,000/ul means what? | Thrombocytosis and may indicate excessive clotting |
platelet count of less than 150,000/ul indicates what? | thrombocytopenia and may cause bleeding |
measures the settling rate of RBC's (which increases often in the inflammatory processes where there is increased destruction of RBC's) | ESR = erythrocyte sedimentation rate |
RBC contains "A" antigens | blood type A |
RBC contains "B" antigens | blood type B |
RBC contains both "A" and "B" antigens | blood type AB |
RBC contains * NO * antigens | blood type O |
RBC has "D" antigen | Rh positive |
RBC does not have the "D" antigen | Rh negative |
measures protein bound iron circulating in serum | serum iron |
measures amount of protein available that carry the iron from tissues to bone marrow which include the amount of transferrin present | TIBC = total iron bindinf capacity |
an iron storage protein directly relates to amount of iron body stores | ferritin levels |
what test can be used to evaluate lymph nodes, liver, or spleen? | CT or MRI Scans |
what test is used to detect malignancies? Indicate increased activity which may be typical in tumors/malignancies. Tracer highlights "HOTSPOTS" | PET SCAN (positron emission tomography) |
Preferred site for a bone marrow biopsies | Posterior Iliac Crest |
lymph node biopsy done via a small needle aspiration, direct pressure applied after procedure | Closed Biopsy |
lymph node biopsy where an actual incision is made, lymph node is excised, local or general anthesia is used | Open Biopsy |
