Term
Hemorrhagic anemia
Definition
result of blood loss
Term
Pernicious anemia
Definition
deficiency of vit B12; IF not being secreted due to autoimmune dysfunction
Term
aplastic anemia
Definition
disorder of the red bone marrow
Term
Thalassemias
Definition
genetic; inadequate production of normal hgb; abnormal production of hemoglobin (major- cant compensate) (minor-can compensate)
Term
Polycythemias
Definition
too many RBC's
Term
hemolysis
Definition
increased destruction (ex: sickle cell)
Term
iron deficiency anemia
Definition
malabsorption, inadequate intake, loss of iron in the blood through GI and GU system, pregnancy
Term
Megaloblastic anemias
Definition
a number of these; DNA synthesis impaired leads to defective RBC maturation; large and abnormal, destroyed easily
Term
folic acid deficiency (megaloblastic anemia)
Definition
necessary for DNA synthesis leading to RBC formation and maturation
Term
pancytopenia
Definition
decreased RBC, WBC, and platelets
Term
aplastic anemia
Definition
Congenital or acquired due to environment, infections, medications, or idiopathic; pancytopenia
Term
intrinsic factors
Definition
within the cell; defects, enzyme deficiencies, genetic factors
Sickle cell
Term
Extrinsic Factors
Definition
Normal RBC, destruction by external factors: trapped in organs, antibody destruction, toxins, mechanical destruction
Term
diagnostics for anemia
Definition
Complete blood count
RBC count
Hemoglobin
Hematocrit
Total iron binding capacity

Plasma infiltrates and destroys the bone by forming tumors
Tumors prevent the bone marrow from producing the cells it needs to
Tumors put pressure on structures where they are growing
Anemia-rbc, wbc, platelets are prevented from being produced
Increases calcium levels in the blood
Term
shift to the left
Definition
relative increase in immature forms of blood cells. The term actually comes from the fact that, if you go back to a patho book and look at the entire cascade diagram of how blood cells mature, the immature cells are on the left side of the old, standard diagram.If the body is producing and mobilizing a large number of new white cells, then the body is attempting to fight off a very active infection.
Term
primary immune system disorders
Definition
impaired immune system; immune system not working correctly
Term
secondary immune system disorders
Definition
over-activity of the immune system; hyperresponsive reaction of immune disorders (autoimmune disorders?)
Term

Definition
