Neutrophil
Eosinophil Basophil |
|
|
Granulocytes
|
Neutrophil
Eosinophil- red stained granules Basophil-blue stained granules |
|
|
Agranulocytes ( lacks the granules)
|
Monocyte and macrophage
Lymphocyte |
|
|
The most predominant leukocytes in the human body |
Neutrophils |
|
|
Neutrophils |
(50-70%)are phygocytes |
|
|
Eosinophil |
(1-3%)phagocytosis of antibody-coated parasites |
|
|
Basophil and Mast cell |
Release of chemical mediators of inflammation and allergies |
|
|
Monocyte and macrophage |
(3-7%)phagocytosis and cytokine secretion |
|
|
lymphocyte |
(25-33%)antibody production ; cytotoxic properties; cytokine secretion |

|
Lymph |
is the clear fluid surrounding tissue cells and filling intercellular spaces |
|
|
skin and skin penetration |
skin protects the deeper tissues of the body |
|
|
Mucous membranes |
lines the epithelium of the digestive and respiratory tracts--prevents penetration of parasites into tissues
|
|
|
Natural killer cells
|
recognize and kill abnormal cells (any cells infected with bacteria, cancer cells, or organ transplants)
|
|
|
Three component pathways |
Alternative complement pathway Lectin complement pathway Classical pathway- antigen-antibody interactions that occur during specific immune responses |
|
|
Which of the following is not true about Natural killer cells? |
Natural killer cells produce 20 complement proteins to enhance phagocytosis through inflammation and opsonization |
|
|
Phagocytosis |
Process of "cell eating" |
|
|
Toll-like receptors are signaling receptors on: |
macrophages dentritic cells endolethial cells
|
|
|
Inflammation |
nonspecific defensive response by the body to an injury in the tissue |
|
|
4 characteristics signs of Inflammation |
Rubor- redness from blood accumulation of calor- heat from warmth of the blood Tumor- swelling from the accumulation fluid Dolor-pain from injury to local nerves |
|
|
which of the following properties is common to macrophages and neutrophils? |
Ability to pahogocytes |

secondary lymphoid tissues |
spleen and lymph nodes |
|
|
Specialized cells of lymph nodes |
tonsils, adenoids, spleen, Peyer's patches of the small intestine and appendix |
|
|
opsonins |
attached to microbes to increase the ability of phagocytes to adhere (opsonization) |
