Where are plasma proteins made? - correct answer-✅liver
formed elements: - correct answer-✅RBCs, WBCs, platelets
RBCs - correct answer-✅carry oxygen to tissues
WBCs - correct answer-✅defend against infection
Platelets - correct answer-✅control bleeding
albumin - correct answer-✅important for pressure between vessels
globulins - correct answer-✅blooding clotting and immune
prothrombin and fibrinogen - correct answer-✅clotting factors, coagulation
Hematocrit - correct answer-✅-Plasma: 55%
-Buffy coat: >1%
-Formed elements: 45%
hematopoeisis - correct answer-✅production of blood cells in bone marrow
erthyropoiesis - correct answer-✅production of RBCs
Leukopoiesis - correct answer-✅production of WBCs in bone marrow
thrombopoiesis - correct answer-✅development of platelets
RBC life span - correct answer-✅120 days
hemoglobin - correct answer-✅the oxygen-carrying protein in blood, contains globulins and heme,
needs amino acids, vitamin B and iron
erythropoietin - correct answer-✅-a hormone that stimulates the production & maturation of RBCs
-secreted by the kidney
-tissue hypoxia
deficiency of RBCs - correct answer-✅anemia
, high levels of RBCs - correct answer-✅erythocytosis, polycythemia vera
Granulocytes - correct answer-✅neutrophils, eosinophils, basophils
Agranulocytes - correct answer-✅monocytes and lymphocytes
Neutrophils - correct answer-✅Most abundant and most common, last 4 days, first responders to injury,
phagocytize and respond to infection
Eosinophils - correct answer-✅parasitic infections
basophils - correct answer-✅become mast cells that release histamine and heparin
Lymphocytes - correct answer-✅T and B cells
Monocytes - correct answer-✅become macrophages that phagocytize
Low leukocyte count - correct answer-✅leukopenia, aka neutropenia
high leukocyte count - correct answer-✅leukocytosis
Thrombocytes (Platelets) - correct answer-✅essential part of the clotting process
Thrombopoietin - correct answer-✅stimulates production of platelets
platelets circulate for ________ before losing function - correct answer-✅10 days
Where are platelets destroyed - correct answer-✅spleen
aggregation - correct answer-✅stick to each other. forms a "platelet plug" that seals small breaks in
blood vessels
Low thrombocyte count - correct answer-✅thrombocytopenia
high thrombocyte count - correct answer-✅thrombocytosis
hemostasis - correct answer-✅clotting cascade
initiation of clotting cascade - correct answer-✅-damaged tissue and pits release factors that stimulate
a cascade producing prothrombin activator
-converts prothrombin to fibrinogen to clot
intrinsic hemostasis - correct answer-✅within the vessel, SLOW
extrinsic hemostasis - correct answer-✅fibrin will create stronger clot to make the plug, external, FAST
Platelets - correct answer-✅1st responder to bleeding, plug the hole
fibrin - correct answer-✅secure the clot from tears
peripheral blood smear - correct answer-✅draw blood with complete counts
complete blood count - correct answer-✅The number of RBC's (red blood cells), WBC's (white blood
cells) and platelets (per cubic millimeter) that are present in the patient's sample of blood is determined.
studies for bone marrow function - correct answer-✅bone marrow biopsy, iron studies, transferrin,
reticulocyte count, ferritin, folic acid levels, B12
bone marrow biopsy - correct answer-✅microscopic examination of a core of bone marrow removed
with a needle
Coagulation studies - correct answer-✅ACT, PT, PTT
ACT - correct answer-✅activated clotting time- platelet function
PT - correct answer-✅prothrombin time- extrinsic
PTT - correct answer-✅partial thromboplastin time- intrinsic
RBC count - correct answer-✅4-6 million
Hemoglobin count - correct answer-✅adult male: 14-16 g/dl
adult female: 12-16 g/dl
hematocrit - correct answer-✅3 x Hgb
Male: 40-54%
Female: 38-48%
WBC count - correct answer-✅5,000-10,000/mm3
Platelet count - correct answer-✅150,000 - 350,000 mm3
Anemia - correct answer-✅Reduction in the total number of erythrocytes in the circulating blood or in
the quality or quantity of hemoglobin
