Basophilia
blue stain (red also) ?
What are the 5 components of blood?
erythrocytes
leukocytes
platelets
plasma
Azurophilia
violet stain?
Eosinophilia
a stain
Neutrophilia
a stain
Erythrocyte
what gives color to blood 45% blood volume higher in people in high altitudes function: transport biconcave
Spectrin
Component of RBC
Platelets
Visualized as a purple dot.
150k to 450k
function: clotting
Granulomere
Part of platelets
where all the ‘action’ is, does the clotting
Leucocytes
has classifications
Granular / Polymorphonuclear
Neutrophils
Basophils
Eosinophils
Non-granular / Mononuclear
Monocyte
Lymphocytes
Neutrophils
Most numerous WBC
Nucleii has many lobes / segments (trademark)
More lobes = older
function: fights bacteria
go out of the blood vessels, exits through capillaries
Drumstick (neutrophils)
Corresponding to inactive X chromosome in females
Diapedesis
Exit of cells to capillaries
Chemotaxis
Process of neutrophils going to the area of infection
Granules (in neutrophils)
responsible for killing the bacteria the neutrophils ingest
Pus
Signifies dead neutrophils
Eosinophils
trademark: pink-staining granules, bilobe structure of nucleus
associated with parasitism and allergy
found in GI tract, respiratory tract, spleen
manifestation: bloated stomach, malnourished (parasites)
Basophils
structure: bilobe
trademark: darker granules than epsinophils
least # of WBC in smears
Turns red or pink in blue pigments
Histamin (basophils)
Notorious in allergic reactions
Anaphylactic shock
blood vessels dilated, etc.
Lymphocytes
Scant cytoplasm, with nucleus
classified as T cells and B cells
the only WBC that returns to blood
T cells
made in the bone marrow, but goes to the thymus
types: helper T cell, suppressor T cell, cytotoxic T cell (killer T cell)
