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
WBCs may be counted visually using a _________ and _________
microscope and
hemocytometer
causes RBCs to lyse or rupture
dilute acid solution
diluent for WBC counting
dilute acid solution
an increase in bands
also signals bacterial
infection
Left shift
Their tasks are to identify
and phagocytize (engulf
and consume) foreign
particles
Macrophages
immature macrophage passing through the blood from its point of
origin, usually the bone marrow,
to a targeted tissue location.
Monocyte
decrease in neutrophils
has many causes, but
it is often caused by
certain medications or
viral infections
Neutropenia
The cytoplasm contains pinkor lavender-staining granules filled with
bactericidal substances.
NEUTROPHILS
an increase in WBC count.
Leukocytosis
are the most
abundant cell type in the body
Macrophages
is an uncontrolled proliferation of a clone
of malignant WBCs
Leukemia
Long term administration:
viral infection
↓CBC count:
↓Neutrophil
is the most
common form of childhood leukemia
Acute lymphoblastic leukemia
phagocytic cells whose
major purpose is to engulf
and destroy microorganisms and foreign material, either directly or
after they have been labeled for destruction by the immune system
NEUTROPHILS
types according to nucleus
- Polymorphonuclear (PMN)
- Mononuclear
is
often associated with drug
therapy or
immunodeficiency.
Lymphopenia or
lymphocytopenia
a decreased WBC count
Leukopenia
leukemia that is more prevalent
in people older than 65 years.
Chronic lymphocytic leukemia
Hematologic disorde; may be
found in certain infections
or in inflammation
Monocytosis
often
signals bacterial
infection.
NEUTROPHILS
you may also used WBC counting in analyzing:
cerebrospinal fluid or pleural fluid
The term segmented refers
to their multilobed nuclei
NEUTROPHILS
Macrophages assist the
lymphocytes in mounting
an immune response
through the assembly and presentation of
antigen
epitopes.
Directly involved in
attacking the bacteria in
any part of the body
especially the blood
NEUTROPHILS
comprise a complex system of
cells that provide for host
immunity
LYMPHOCYTES
reference range for WBC
5,000-10,000/cumm
technique for celll counting
Hemocytometry
