| What types of white blood cells are there? |
|
Definition
| Monocytes, lymphocytes, eosinophil, neutrophil, basophil |
|
|
Term
|
Definition
| Neutrophils, eosinophils, and basophils are called granular leucocytes because all have cytoplasmic granules that are visible through a light microscope when stained. |
|
|
Term
|
Definition
| Lymphocytes and monocytes are called agranular leukocytes because the cytoplasmic granules are not visible under a light microscope because of their small size and poor staining qualities. |

|
|
Term
| 3 major categories of plasma are: |
|
Definition
| Albumins: most abundant & important, produced by liver, contributes to viscosity. Globulins: Antibodies, provide immune system functions, produced by plasma cells. Fibrinogen: help form blood clots, produced by liver |

Term
|
Definition
| Starts in the red bone marrow with a proerythroblast, which divides several times producing a colony-forming unit, then a erythroblast, which ejects its nucleus and becomes a reticulocyte which develops into a mature red blood cell (erythrocyte) within 1 to 2 days. |

|
Definition
| Opposing Rh blood in woman and fetus, 1st pregnancy ok, however during 1st pregnancy the woman will develop antibodies which will cross the placenta during the 2nd pregnancy and could cause hemolytic disease of newborn. RhoGAM vaccine which binds to the fetal agglutinogens could prevent this disease. |
