-
3 causes of anemia
- 1) inadequate erythropoiesis or hemoglobin synthesis
- 2) hemorrhagic anemia from bleeding
- 3) hemolytic anemia from rbc destruction
-
type of white blood cell that phagocytize bacteria, and release antimicrobial chemicals (bacteria chopper)
neutrophil
-
type of wbc that secrete histamine, and heprin
basophil
-
type of WBC that phagocytize antigen-antibody complexes, allergens, and inflammatory chemicals, release enzymes, and destroy paracytes. (paracytes and phagocytize allergens)
eosinophil
-
type of wbc that destroy cancer cells, infected cells, and foreign cells.
they present antigens, secrete antibodies, and coordinate immune defenses. (immune system)
lymphocytes
-
type of WBC that differentiate into phagocytize pathogens, dead neutrophils and debris of dead cells, and present antigens to activate immune system. (phagocytize debris).
monocytes
-
- 1) SA node fires
- 2) signal spreads through out atrial myocardium
- 3) AV node fires
- 4) excitation spreads down AV bundle
- 5) purkinje fibers distribute excitation through ventricular myocardium
