    • erthrocytes
    • red blood cells shaped like biconcave disks which lack a nucleus and are small in size, compared to white blood cells,they transport oxygen to and carbon dioxide from the tissue
  1. leukocytes
    white blood cells have various shapes and size. they are named based on how they stain. they are nucleated and the nucleus is often distinctive. wbcs are an important part of the bodys defensive system.
  2. what are the two types of wbcs
    • granulocytes
    • neutrophils
  3. granuoctes
    the category of wbcs containing membrane bound granules
  4. neutrophils
    the nucleus of the granlocytes stains deeply and exhibits multiple lobes. the cytoplasm does not stain but will appear pale, with many fine granules. these wbcs destroy bacteria
  5. eosinophils
    the nucleus of these granulocytes usually has two darkly stained loves connected by a thin strand. the cytoplasm contains large granules that stain reddish orange. these wbcs phagocytize antibody antigen complexes and attack some parasitic worm
  6. basophils
    the nucleus of these granulocytes exhibits two lobes which are difficult to see because of the large and dense blue stained granules. the granules aid in the inflammation process by releasing histamine
  7. agranulocytes
    the category of wbcs lacking membrane bound granules
  8. lymphocytes
    the nucleus is round,, or slightly oval, and almost fills the cytoplasm. the nucleus stains dark blue to purple, and the cytoplasm is usually light blue. these agranulocytes are involved in specific disease resistance. b cells, and natural killer cells are types of lymphoctes
  9. monocytes
    the nucleus is a kidney bean or horse shoe shape. the nucleus stains darkly and the abundant cytoplasm is a pale blue. these arganulocytes develop into phagocytic macrophages.
  10. precava and post cava
    these are two large veins that enter the right atrium and carry unoxygenated blood from the superior and inferior body, respectively
  11. right atrium
    this is the first chamber of the heart and receives unoxygenated blood from the body
  12. tricuspid or right atrioventricular valve
    this valve separates the right atrium and ventricle. it prevents back flow into the atrium
  13. pulmonarsemilunar valve
    this valve separates the pulmonary trunk from the right ventricle and prevents back flow into the ventricle
  14. right ventricle
    this is the second chamber of the heart and pumps blood to the lungs
  15. pulmonary arteries
    these arteries carry unoxgenated blood from the right ventricle to the lungs
  16. pulmonary veins
    these veins carry oxygenated blood from the lungs to the left atrium
  17. left atrium
    this is the third chamber of the heart and receives oxygenated blood from the lungs
  18. bicuspid, mitral or left atrioventricular valve
    separates the left atrium and ventricle it prevents back flow into the atrium
  19. left venttricle
    this is the forth chamber of the heart and pumps oxygenated blood to the body
  20. aortic semiounar vavle
    this valve separates the aortic arc from the left ventricle and prevents back flow into the ventricle
  21. aortic arch and aorta
    this is the largest elastic artery in the body and carries oxygenated blood to the body
  22. chordae tendonae and papillary muscles
    these are the heart strings and the muscles that control the tricuspid and bicuspid valves
  23. coronary arteries and veins
    these are the vessels located on and in the actual myocardium or heart muscle. they supply and drain the myocardium of blood respectively
