White blood cell formation/development 71. Precursor cell of platelets 72. Immediate precursor cell of erythrocytes 73. Granulocytes develop from VIl. Platelets&Leukocytes; (slide 19-25)Explanation / Answer
51. whole blood is composed of 55% plasma and formed elements called red blood cells (erythrocytes ), white blood cells (leucocytes ) ,blood platelets and cells make up tpo 45%
52.erythrocytes are the most abundant formed elements in whole blood
53. buffy coat contain blood cells and platelets
54. the hemocrit is the volume % of red blood cells . im men 45% and women have 40%
55. higher than the normal hct means dehydration , low availability of oxygen , genetic erythrocytosis .
56.plasma is liquid component of blood contains red blood cells ,white blood cells , platelets are suspended . its constitutes more than half of the blood volume and water
57.most abundant plasma protien is albumin
58.fibrinogen which forms fibrin network traps cellular components of blood in clot clotting of blood needs presence of other clotting other clotting factors as well . hence serum may lack many clotting factor , fibrinogen is clotting factor 1
59 yes fibrinogen contain 7% of blood proteins conversion of fibrinogen in to insoluble fibrin is essential for blood clotting
60. synthesised in the liver except gamma globulins
61. consists of protein group globin, four heme group associated with iron atom
62.oxygen binds to red blood cells to react
63.oxyhaemoglobin
64. co2 binds to globin protein of hemoglobin
65.billirubin breakdown products are stercobilin, cause the brown colour in feac
66.erythrocytes have no oraganelles
67. formation of red blood cells called erythropoiesis
68 kidney secrets erythropoietin
69.. hemopoieses begins in the red bone marrow with hemopoeitic stem cells differentiates in to myleoid and lymphoid lineages ., most stem cells are myeloid
70 white cells are produced by multipotent cells in the bone marrow called hemopoietic stem cells
71.megakaryocytes are precursor cell of platelets
72.normoblast is the normal,or healty cells are immediate precursor cell of erythrocytes
73. a type of immature white blood cells that form in the bone marrow . myeloblasts become mature whiote blood cells called granulocytes
74 platelets are the cells fragements from megakaryocytes
75.no mature cells are have no nuclei
76. lymphocytes and monocytes
77. the fribrin proteins stick together forming a clot .clotting cascade occurs two seperate poathways called extrinsic and intrinsic pathway
78. blood coagulation pathway ,thrombin acts as to convert 11 to 11a , 8 to 8a, 5 to 5a ,fibrinogen to fibrin ,13-13a, factor 13a is a transglutamine that catalyses the formation of covalent bonds between lysine and glutamine residues in fibrin
79 plasma protein called fibrinogewn is converted to fibrin
80. suffer from blood clotting ,bleeding ,bursing ,alzemers diseases
81. a proteolytic enzyme fromed from plasminogen
82. first phase is vasuclar spasm or vasoconstriction , a breif and intense concentration of blood vessels
time is over .resend the second paper i will answer
