Describe the hierarchy of the immune system in terms of white blood cells Immune System-> White Blood Cells-> Agranulocytes-> Lymphocytes-> B & T Lymphocytes Lymphocytes -Type of white blood cell in the immune system, made by bone marrow -Includes: T-Cells, B Cells, and Natural Killer (NK) cells (Cytotoxic T Cells) --All of these help to fight cancer, Viruses, and Bacteria B Cell Lymphocytes -Have receptors where antigens attach -They learn to recognize different antigens -...

Mediators - ANSWER-Immune cells release proteins that mediate inflammation and in the destruction of agents foreign to the host (interferons, interleukins, and immunoglobulins) Two main parts of the immune system - ANSWER-1) Innate Immune System 2) The Adaptive Immune System White blood cells of the innate immune system - ANSWER-1) Monocytes 2) Granulocytes (Neutrophils, Eosinophils, Basophils) 3) Natural Killer (NK) Cells Two types of T-lymphocytes - ANSWER-1) Cytotoxic T-cells 2...

lymphocytes - types of white blood cells; function in innate and adaptive immunity; both types originate from stem cells located in bone marrow B cells - lymphocytes that remain in bone marrow in process of maturation T cells - lymphocytes that migrate to thymus antigen - any foreign substance that elicits a B or T cell response; most are proteins or large polysaccharides epitope - specific region that is exposed on the surface of antigen molecule; binds to antigen receptor; each B and T ...

How many antigen binding sites does a T cell receptor have and how many binding sites does B cell have? - One; Two During somatic recombination of both B/T cell variable regions, 12/23 rules is observed. - TRUE Binds to FC receptors on mast cells and is involved in allergic reaction - IgE Antibodies can: - * Act as opsonins * Neutralize a toxin or virus How many subclasses of IgG are there? - 4 Switch sequence or with regions are found at the beginning of each constant region gene. - IgD ...

List First and Second Line of Defense for INNATE IMMUNITY -intact skin -mucous membranes -normal microbiota -natural killer cells and phagocytic white blood cells -inflammation -fever -antimicrobial substances List Third Line of Defense for ACQUIRED IMMUNITY -specialized lymphocytes: T cells and B cells -antibodies A child falls and suffers a deep cut on her leg. The cut went through her skin and she is bleeding. Which of the following defense mechanisms will participate in eliminating contami...

PIONEER ISBBCross-reactivity A phenomenon that occurs when an antibody reacts with antigen that is structurally similar to the original antigen that induced antibody production Karl Landsteiner This person Immunized rabbits with haptens attached to a carrier molecule and then tested the serum to measure how the antibodies produced reacted with different haptens Ability of the individual to resist infection by means of normally present body functions Characteristic of natural imm...
