White Blood Cells

QuestionAnswer
Another name for white blood cells: Leukocytes
ALL circulating WBCs have these 4 characteristics: 1)Can migrate out of blood stream. 2)Are capable of amoeboid movement. 3) Are attracted to specific chemical stimuli 4) Neutrophils, Eosinophils, and Monocytes are phagocytic.
Which WBC's are phagocytic? Neutrophils, Eosinophils, and Monocytes
The amoeboid movement of WBC's allows for easy movement from blood to ______ ______. peripheral tissues
WBC's are attracted to specific chemical stimuli, which guides them invading pathogens, damaged tissue, and other WBC's. This is called _______ _______. positive chemotaxis
The 2 categories of WBC's are: 1) granular 2) agranular
WBC's are produced primarily by ______ ______ ______. red bone marrow
Which WBC's migrate early in their development from the red bone marrow to lympatic structures like the spleen, lymph nodes, and thymus - granular or agranular? agranular
What is Leukopenia? Low WBC count.
What are some causes of leukopenia? chemotherapy, radiation therapy, medications, nutrition, infection, forms of leukemia, autoimmune disorders.
What is Leukocytosis? High WBC count
What are some causes of Leukocytosis? Modestly high may indicate some infection. Extremely high may indicate a form of leukemia.
Name the WBCs in order of abundance in the blood, starting with the most abundant: 1) Neutrophils 2) Lymphocytes 3) Monocytes 4) Eosinophils 5) Basophils
Which WBC's are granular? Neutrophils, Eosinophils, Basophils
Which WBC's are agranular? Lymphocytes & Monocytes
Which WBC? -- The body's 1st line of defense against bacterial infection. The most abundant WBC. Is phagocytic. Neutrophils
Which WBC? -- The body's 2nd line of defense against infection. They follow Neutrophils to the cite of infection. These are the precursors to macrophages. Are phagocytic. Monocytes
The activity and death of these WBC's in large numbers forms pus: Neutrophils
The WBC that primarily deals with parasitic infections: Eosinophils
WBC responsible for antibody production: Lymphocytes
WBC that is chiefly responsible for releasing the chemical histamine in response to allergic and antigen response, causing inflammation: Basophils
WBC with odd-shaped multilobed nucleus and small pinkish-red granules Neutrophils
WBC with LARGE red granules and a bi-lobed nucleus Eosinophils
WBC with dark blue-black granules that almost obscure the cell's neucleus. Basophils
WBC with no granules in cytoplasm and a nucleus that is puffy and "U" shaped Monocyte
WBC with no granules in cytoplasm and a super huge, round nucleus Lymphocyte
WBC that is called a macrophage when it is OUTSIDE of the blood: Monocyte
Cellular fragments which have broken away from metamegakaryocytes in red bone marrow: thrombocytes (or platelets)
Thrombocytes/platelets are not really cells - they are cellular fragments that contain thromboplastin which interacts with other components to initiate the formation of a ______ _____. blood clot
