*HEMATOLOGY*


BLOOD: is a type of connective tiss


* RED Blood Cells {RBC}- "Erythrocytes"* WHITE Blood Cells {WBC} - "Leukocytes"* Platelets/Thrombocytes - "Fragments" / "Clotting Cells"* Plasma - "The Fluid part of the blood"


Blood Components:


*Hematocrit* {Hematocrit is a blood test that measures the percentage of the volume of whole blood that is made up of red blood cells} - % of RBC is normally 45% - % of WHB & Platelets is normally 1%- % of Plasma is normally 55%


A.) RED BLOOD CELLS: ERYTHROCYTES


* Transport 02 thru the bdy* Small bi/concave - shaped cells* Hemoglobin is a pigment of the RBC's* Erythropoietin - regulates production of RBC's


B.) W.B.C/LEUKOCYTES:

*GRANULOCYTES/PMN'S*...
"PMN: Polymorphonuclear Leukocytes"


1.) Neutrophils = 55% - destroy bacteria, viruses & toxins in the blood stream {Phagocytes}


B.) W.B.C/LEUKOCYTES: *GRANULOCYTES*.


2.) Eosinophils = 3% - Gets rid of parasitic infections; such as, "Worm Infection"


B.) W.B.C/LEUKOCYTES: *GRANULOCYTES*.


3.) BASOPHILS: = 1% - Controls inflamation & allergic reaction


B.) W.B.C/LEUKOCYTES: *AGRANULOCYTES*


1) MONOCYTES: 8% - Destroy bacteria, viruses, & toxins in the blood.


B.) W.B.C/LEUKOCYTES: *AGRANULOCYTES*


2) LYMPHOCYTES: 33% - Provides immunity in the body- WBC count is normally 5, 000 2 10,000 cells per/cubic milimeter of blood.


B.) W.B.C/LEUKOCYTES: *AGRANULOCYTES*


2a) *LEUKOCYTOSIS: - Elevated blood cell count, usually due 2 infection {abnormal condition of W.B.C}


B.) W.B.C/LEUKOCYTES: *AGRANULOCYTES*


2c) *LEUKOPENIA: - Low WBC ct usually due 2 Viral Infections & other conditions {Decreased amt in WBC}


C.) PLATELETS: *THROMBOCYTES*


* Fragments of cells found in the bloodstream* Important in the clotting process of blood* Normal Ct: 130,000 2 360, 000 platelets per/cb mm {per cubic milimeter} of blood


D.) PLASMA:


* 55% of blood * Liquid portion of the blood composed mostly of water, but it also contains:
- PROTEINS - NUTRIENTS- GASES {O2 & CO2} - ELECTROLYTES - WASTE PRODUCTS


I.) BLEEDING CONTROL:
"HEMOSTATIS' - The Control of Bleeding


The 3 Processes of Hemostatis: 1) Blood Vessel Spasm2) Platelets Plug Formation3) Coagulation
