Correct
Q: Pluripotent Stem Cell
Answer:
-The cells of the immune system are created in the bome marrow from what is know as a _
-A stem cell that can differentiate into any cell type except for extraembryotic tissue, does not
yet have a function
Q: Myeolid Precursor Cells
Answer:
Mature into:
-RBCS
-Plts
-WBCs (Granulocytes)
Q: Lymphoid Precursor Cells
Answer:
Mature into:
-Specialized WBCs called lymphocytes (Agranulocytes)
Q: Lines of Defense: The Immune System’s Response to Attack
Answer:
Consists of 2 types of immunity:
1: Innate
2: Adaptive
Q: Innate Immunity
Answer:
-First line of defense against a pathogen
-Does not retain memory of the entity
-Involves the following:
(skin, mucous membranes, and normal flora of the skin and gut)
(Cellular components such as phagocytes, natural killer cells, granulocytes, and macrophages)
Q: 1. Phagocytes
- Natural Killer Cells
- Granulocytes
- Macrophages
Answer:
1.Cells that engulf and destroy invader - Cells that sense receptors on self and non-self to determine if they should kill or not
- Type of WBC that have granules (Neutrophils
Eosinophils – parasites
Basophils – release histamine to stimulate immune response) - Large phagocytic cells stimulated by infection
Q: Adaptive Immunity
Answer:
-Stimulated if innate immunity is insufficient
-leads to immune system memory
-Humoral immunity
-Cell-mediated immunity
-Regulatory T-cells
Q: Humoral Immunity
Answer:
-B-Cells
-Memory B-Cells
-Plasma act to produce immunoglobulins (Igs) or antibodies
Q: B-Cell
Answer:
-each one is programmed to make one specific antibody
-Can recognize antigens whether they are freely circulating in the blood or attached to surface of
a microbe
-When dividing, can become plasma cells which will then begin secreting antibodies that are
unique to that antigen
Q: Plasma Cells
Answer:
-some plasma cells will undergo apoptosis
-Some will go to the BM where they will continue to secrete antibodies sometimes for years
Q: Cell-Mediated Immunity
Answer:
Depends upon cytotoxic T cells and helper T cells and their cyokinds
-more effective against antigens within cells
Q: Regulatory T-cells AKA suppressor T-Cells
Answer:
regulate the immune response to prevent autoimmune reactions and limit inflammatory
responses
Q: T-Cell
Answer:
-Can only recognize antigens when they are presented to them by “presenting cells”
-Recognize phagocytized fragments of an antigen that are put on the surface of antigenpresenting cells
Q: Helper T-Cells (CD4+)
Answer:
-help other T-Cells by secreting chemicals
-Help B Cells to respond
-rapidly divide, in an effort to stay ahead of the antigen dividsion
-some will turn into effector cells, which secrete different kinds of cytokines
-respond similarly to B-Cells
