Card Set Information
histology lab blood
contains formed elements—erythrocytes, platelets, leukocytes; also plasma.
Transport of gases (oxygen and carbon dioxide), ions, proteins and lipids among other things.
60-70% circulating leukocytes, divided into two to five segments or lobes, light-staining.
Phagocytosis of foreighn cells, toxins, and viruses; involved in bacterial infections.
Small lobe protrudes from the nucleus, known as "drumstick." It represents the inactive sex chromosome of the cell (Barr body).
Found solely in females.
Constitute 2-4% of circulating Leukocytes. Bilobed nucleus, reddish-orange granules.
Effective against parasitic-worm infections; involved in allergic reactions.
0.5-1% of circulating Leukocytes (least numerous of all leukocytes). Nuclei stain dark blue-purple, numerous dark granules may sometimes mask the nucleus.
A role in allergic responses. Granules contain histamines (vasodilators) and heparin (anticoagulant).
Large dark purple staining nucleus with thin rim of pale blue cytoplasm; accounts for 255-35% of circulating leukocytes.
B-cells involved in humoral immunity and produce antibodies; T-cells involved in cell-mediated immunity to destoy foreign cells.
More abundant and basophilic cytoplasm than small lymphocytes; also cytotoxic or natural killer cells; may function in absence of antibodies.
Destroy tissue grafts, tumor cells, and cells infected with viruses through production of perforins.
3-8% of circulating leukocytes. Kidney-shapped or horseshoe-shaped nucleus.
Migrate into tissues, where they become macrophages and sere in phagocytosis of foreign particles such as viruses and bacteria.
Increased neutrophil count.
Cause: Bacteria Infection.
IRON DEFICIENCY ANEMIA
Anemia: Messes up with the form of erythrocytes. Not enough healthy red blood cells.
Red blood cells: provide O
to the tissues.
CHRONIC LYMPHOCYTIC LEUKEMIA
There's too many lymphocytes that are about the same size. Occurs over a long period of time.
