define LEUKEMIA
cancer w/progressive increase in abnormal WBC in blood-forming tissues, organs, & blood
define APLASTIC ANEMIA
no formed elements (leukopenia & thrombocytopenia)
describe IRON DEFICIENCY ANEMIA
most common; not enough iron to make hemoglobin
cause: iron-deficiency anemia
blood loss, poor iron absorption, inadequate iron intake
describe MEGALOBLASTIC ANEMIA
blood disorder w/symptom of anemia; RBCs bigger than normal
cause: megaloblastic anemia
deficiency of folic acid/vitamin B12

define ACE INHIBITOR | blocks action of angiotensin II contracting blood vessel to treat hypertension & heart failure |
ACE inhibitor is also known as | angiotensin-converting enzyme |
describe BETA BLOCKER | decrease workload of heart by slowing bpm; treats hypertension, angina, heart failure, heart rhythm disorders, migraines, panic attacks, & tremors |
