Answers
What is hematopoiesis? - answer✔production of blood cells in the red bone marrow
how are red blood cells produced? - answer✔erythropoiesis - activated by erythropoietin
what is hemolysis? - answer✔destruction of red blood cells
what is the main function of red blood cells? - answer✔transport oxygen and acid base balance
what is a band? - answer✔an immature neutrophil
what would cause an increase in neutrophils? - answer✔infection or tissue injury
what is the main function of granulocytes? - answer✔phagocytosis - the process where white
blood cells engulf unwanted organisms, digest and kill them
what is a seg? (segmented neutrophil) - answer✔a mature neutrophil
what are the two types of lymphocytes? - answer✔t cells and b cells
what are natural killer cells? - answer✔lymphocytes that kill and attack virus infected cells
what is the main function of thrombocytes? (platelets) - answer✔start the clotting process by
producing an initial platelet plug at the site of injury

ferritin
fibrinogen
what is leukopenia? - answer✔decreased number of WBC count - 5,000 or less
occurs with bone marrow depression, severe or chronic illness and other types of leukemia
what is thrombocytopenia? - answer✔low platelet count
what is neutropenia? - answer✔low neutrophil count
what is thrombocytosis? - answer✔high platelet count
what is a reticulocyte? - answer✔immature red blood cell
what is the process of clotting? - answer✔vascular injury
local vasoconstriction occurs immediately
platelet response is activated
subendothelial exposure fills gaps
agrigation or adhesion (same thing) - plates join together
activation of the clotting cascade - platelets change shape when the begin to clot
formation of blood clot
clot retraction and dissolusion
what are the most common s/s of iron deficient anemia? - answer✔pallor - most common
glossitis (swelling of tongue)- 2nd most common
inflammation of lips (cheilitis)
headache, paresthesias, burning sensation of the tongue
what are diagnostics of iron deficient anemia? - answer✔low h&h
serum iron will be low
serum ferritin will be low
serum transferrin will be low
total iron binding capacity will be high
