26
Stimulates bone marrow to produce additional RBCs
Erythropoietin (EPO)
27
RBC live ____ days
120
28
Phagocytize materials (clean up;uses pseudopods); Protect from infection
WBC
29
Dead tissue damaged by bacteria; dead WBC
Pus
30
WBC containing granules
Granulocytes
31
Granuclocytes:___ ____ _____
WBC containing granules Neutrophil Eosinophil Basophils
32
Neutrophil
don't stain 55-75% of WBC; seg=mature, bands=mature; phagocytosis
33
Eosinophil
stain red; inflammatory response;^ in parasitic infections
34
Basophils
blue; inflammatory resp.;produce heparin(reduce clotting)
35
Agranulocytes
WBC w/ no granules Lymphocytes Monocytes
36
Lymphocytes
1/3 of WBCs; immune response
37
Monocytes
phagocytotic macophage, fixed and wandering`
38
Platelets
control blood loss
39
Differential White Count
Number of each whites and percentage
40
Complete Blood Count
Bloodtest gives info on # of RBC, WBC, platelets, hemoglobin, hematocrit, maturity of cells
41
Hemostasis & 4 steps
stops bleeding vessel spasm-vessel constricts platelet plug- stick to eachother/damaged tissue clot-chemical reaction=fibrin(net of rbcs&platelets)
42
Clot contraction
Edges of clot pull together; water is squeezed out
43
Pulmonary Embolism
Clot breaks off and gets stuck in lungs
44
Coumadin
Prevents clot formation
45
Thrombus
blood clot
46
Embolus
Traveling Blood clot
47
Blood types based on ___
Antigens in blood
48
Aglutination & Hemolysis & caused by
Clumping of RBCs & RBCs burst caused by bad match in blood
49
