UNIT 1 WBC Flashcards
slightly less mature
neutrophils with a non
segmented
BANDS (band neutrophils,
BANDs)
The basophil granules contain:
histamines and various other proteins
Accompanying
lymphocytosis are often
____________ with
characteristic morphology
reactive lymphocytes
what goes up when you Have
bacterial infection
↑CBC count: ↑WBC:
↑Neutrophils
often
associated with viral
infections
Lymphocytosis
occupy
every body cavity; some
are motile and some are
immobilized.
Macrophages
have a slightly
larger diameter than other
WBCs, blue-gray cytoplasm
with fine azure granules, and a
nucleus that is usually indented
or folded
monocytes
Are cells with round, bright
orange-red cytoplasmic
granules filled with proteins
involved in immune system
regulation.
EOSINOPHILS
is rare and
often signals a
hematologic disease
(Leukemia).
Basophilia
nearly round, are slightly larger than
RBCs, and have round
featureless nuclei and a thin rim
of nongranular cytoplasm.
Lymphocytes
dilutioin for WBC counting
1:20
Cells with dark purple,
irregular cytoplasmic granules
that obscure the nucleus.
BASOPHILS
nucleus in a U or S
shape.
BANDS (band neutrophils,
BANDs)
types of lymphocytes
B, T, and Natural Killer
(NK) cells
recognize foreign
antigens and mount humoral
(antibodies) and cell-mediated
antagonistic responses.
Lymphocytes
Used by the microscopist to differentiate the categories of WBCs in the blood
Wright-stained blood film and light microscopy
often signals and
often a response to
allergy or parasitic
infection
Eosinophilia
comprise a
minor component of peripheral
blood WBCs
monocytes
