ap II lab- types of WBCs (exam 1)

platelets always stain

dark (dark red, or purple)

how can you tell the difference between RBC’s and WBC’s

look at the nucleus- RBC’s dent have a nucleus

nucleus fills up almost the whole cell and leaves a sliver of cytoplasm

• dont confuse with basophil (these are smooth)

lymphocyte

nucleus is horseshoe or kidney bean shaped

• nucleus can spin so it might be “c” or “n” shaped

  • dont confuse with neutrophil… look for the UNIFORM thickness of this nucleus

monocyte

the nucleus looks like a chain of sausages “thick-thin-thick-thin”

• no 2 of these look exactly alike

• somethings the thin area of the sausage might not stain so the sausage looks detached

  • dont confuse with monocyte… look at the thickness of nucleus sausage

neutrophil

full of granules- can’t see the nucleus because the granules cover it

• lumpy texture

• bumpy on the sides of the cell because of granules

  • dont confuse with lymphocyte

basophil

bilobed nucleus (looks like lungs)

• 2 dark sections in its nucleus

• has orange/ red granules in the cytoplasm

eosinophils

order of abundance for WBCs

neutrophils, lymphocytes, monocytes, eosinophils, basophils

• never let monkeys eat bananas
