Question | Answer |
---|---|
What is the development of white blood cells called? | Leukopoiesis |
Where does leukopoiesis occur? | The medullary cavity (bone marrow). Some lymphocytes develop in the thymus (T cells) |
What is another word for white blood cells? | Leukocyte |
How are leukocytes categorized? | By 1) specific function 2) site of origin 3) morphology |
What are the 2 basic types of leukocytes? | Granular and agranular |
Which series of leukocytes has granules in it? (Granular) | Myelocytic series |
Which series of leukocytes has no granules in it? (Agranular) | Lymphocytes and monocytes |
Where are the 4 locations for granulocytes in the body? | 1) bone marrow 2) circulating blood 3) marginal pool/endothelial lining 4) tissues |
What is the first stage of a granulocyte's development? | Myeloblast |
What is the 2nd stage of a granulocyte's development? | Promyelocyte |
What is the 3rd stage of a granulocyte's development? | Neutrophil Myelocyte |
What is the 4th stage of a granulocyte's development? | Neutrophilic Metamyelocyte |
What is the 5th stage of a granulocyte's development? | Neutrophilic Band |
What is the 6th stage of a granulocyte's development? | Neutrophilic Segment |
What is the primary function of a neutrophilic segment cell? | Phagocytosis |
What are the 3 stages of phagocytosis? | 1) migration and diapedsis 2) opsonization and recognition 3)phagocytosis, killing and digestion |
__ is the movement of the seg through the vessel wall. | Diapedesis |
Directional migration to the site of an injury is called __. | Chemotaxis |

__ destroy old red blood cells. | monocytes |
Monocytes migrate into tissue to become __. | macrophages |
Macrophages are basically __ in the tissue. | monocytes |
__ are anti-tumor cells. | macrophages |
