WBC's Flashcards
What are the 2 main functions of Leukocytes?
Phagocytosis and Immunity
What is considered the White Blood Cell’s method of Defense?
Phagocytosis
What are the 3 stages of Phagocytosis?
- Chemotaxis (Attraction)
- Adherence (Binding)
- Ingestion (Endocytosis)
Which Leukocytes are Phagocytic?
Neutrophils, Eosinophils, Basophils, and Monocytes
What Leukocyte is considered an Immunity Cell?
Lymphocyte
(T Lymphocyte and B Lymphocyte)
List the Series of Cells of Leukopoiesis as it takes place in Bone Marrow
Myeloblast (Stem Cell)
Promyelocyte
Myelocyte
Metamyelocyte
Band (Peripheral)
Mature Leukocyte (Segmented)
The Process by which Leukocytes pass through an intact blood vessel to enter into a tissue
Diapedisis
Population of White Blood Cells that are actively circulating through the blood stream.
Circulating Pool
Population of White Blood Cells that are adhered to the endothelium of blood vessels or “Parked” waiting to be mobilized when needed.
Marginating Pool
Physiologic Factors that determine Variations in Leukocytes.
Stress, Exercise and Age
Pathologic Factors that determine Variations in Leukocytes
- Endocrine
- Infections
- Immune-Mediated
- Neoplasia
How do Leukocytes vary between species?
Reference Ranges and Appearance
