WBC

White blood test

TermDefinition
Categories of Leukocytes Granular and nongranular
Granular leukocytes Neutrophils, Eosinopihls, and Basophils
Nongranular leukocytes Lymphocytes and Monocytes
Range of Neutrophils 40%-75%
Range of Eosinophils 1%-6%
Range of Basophils 0%-2%
Range of Lymphocytes 20%-40%
Range of Monocytes 3%-10%
Diapedesis Movement of the WBC through the capillaries
Phagocytosis The engulfing and destruction of pathogens and damaged cells
Pus contents dead leukocytes, dead bacteria, and dead tissue cells
Normal value for WBC 4,500 to 11,000/ mm cubed
Suppuration infected area
location of WBC mostly resides in connective tissue and throughout the body
Granular contains distinct granules in cytoplasm
Non-granular contain few or no granules in cytoplams
Leukocytosis Increase in leukocytes
Cause of Leukocytosis pathological and physiological conditions
Pathological conditions are associated w/ infectious mononucleosis, pneumonia, chicken pox, appendicitis, tonsillitis, hemorrhaging, and Leukemia
Physiological conditions are associated w/ emotional stress, exposure to cold conditions, menstruation, Pregnancy and labor, strenuous exercise
Leukopenia decrease in leukocytes
Conditions associated w/ Leukopenia Cirrhosis, infectious hepatitis, bone marrow depression, chemotherapy, radiation therapy, viral infection
Neutrophils Most common and most numerous WBC
First responders Neutrophils
2 types of Neutrophils segmented and non-segmented
bands or stabs non-segmented parts
Life span of the neutrophil few days
Production of neutrophils takes place in the bone marrow
Amoebic movement a crawling like movement in which the cell forms temporary projections called pseudopodia to be able to move
Pseudopodia False feet
Neutrophilla increase in neutrophils
Neutrophilla is associated w/ acute bacterial infection infections, parasitic infections, liver disease
Neutropenia Decrease in neutrophils
Neutropenia is associated w/ Acute viral infection, blood diseases, hormone disease, and chemotherapy
Location of Neutrophils moves through veins into tissue
Lymphocytes Smallest and 2nd most common white blood cells
Life span of lymphocytes 2 weeks to several years
3 types of of lymphocytes B cells, T cells, and natural killer cells
Lymphocytosis Increase in lymphocytes
Conditions associated with lymphocytosis Addison's disease, acute and chronic infections, lymphocytic leukemia, carcinoma, and hypothyriodism
Lymphopenia decrease in lymphocytes
Conditions associated with lymphopenia Aids or HIV infections, cardiac failure, cushing's disease, hodgkin's disease, leukemia
Monocytes Largest of WBCs
life span of monocytes several months
Monocytosis Increase in monocytes
Conditions associated with monocytosis Viral infection, bacterial and parasitic infections, collagen disease, and cirrhosis
Monocytopenia Decrease in monocytes
Conditions associated with Monocytopenia prednisone treatment and hairy cell leukemia
Eosinophils contains a segmented nucleus, generally no more than 2 lobes
Life span of eosinophils 8-12 days
Eosinophilla increase in eosinophils
Eosinophilla is associated with Allergic reactions, parasitic infections, Addison's disease, Lung and bone cancer
Eosinopenia decrease in eosinophils
Eosinopenia is associated with Infectious mononucleosis, congestive heart failure, aplastic and pernicious anemia, and hypersplenism
Basophils least numerous of WBCs and has a S-shaped nucleus
Granules of basophils contain Histamine and heparin
Basophilla Increase in basophils
Basophilla is associated with Chronic inflammation, leukemia, and hodgkin's disease
Basopenia decrease in basophils
Basopenia is associated with acute allergic reactions, hyperthyroidism, steroid therapy
