The effects of vasodilation during an inflammatory response cause which of the
following?
Slower blood viscosity
Which of the following is a role of histamine when released by mast cells?
Increased Vascular Permeability
Which of the following results when histamine attaches to the H1 receptor?
Smooth muscle contraction, increased chemotaxis, stimulation of prostaglandin synthesis
Which chemical mediator is responsible for prolonged asthma symptoms such as
bronchoconstriction and inflammation?
Leukotrienes
Which of the following are an active modulator of allergic reactions in the immune
system?
Eosinophils
directs movement of cells along a chemical gradient attracting eosinophils and
neutrophils to the site of inflammation.
Chemotaxis
What are the functions of interferons?
Protect against viral infection, modulate inflammatory response
,Your patient has seasonal allergic rhinitis. Which type of hypersensitivity reaction is
this?
Type 1
Your patient has diagnosis of Grave's disease. Which type of Hypersensitivity reaction
is this?
Type 2
Which of the following is a type III hypersensitivity reaction?
Glomerulonephritis
Which of the following statement is true regarding Type IV Reactions?
The reaction is mediated by T lymphocytes
Which of the following statements are true regarding exotoxins?
damage cell membranes, activate second messengers, inhibit protein synthesis
immunity is produced by an individual after natural exposure to an antigen or after
immunization
Active
immunity produces immunoglobulins that bind to antigens and neutralize their effects
Humoral
stimulates the proliferation of T cells and B cells during inflammation
Interleukins
Catecholamines decrease which of the following immune system cells during chronic
stress?
, Natural Killer cells
interfere with insulin signaling leading to insulin resistance in stress, obesity, and Type
2 Diabetes.
Pro-inflammatory cytokines
what type of immunity is produced when an immunoglobulin crosses the placenta?
Passive acquired
the normal microbiome
The body's surfaces are colonized with a variety of microorganisms, Surfaces, such as skin
and mucous membranes of eyes, upper and lower GI tracts, urethra and vagina are colonized
by a combination of bacteria and fungi that are unique to a particular location and individual.
If immunocompromised the microbiome can lead to
opportunistic infections or loss of integrity of the body surface areas.
Type 1 hypersensitivity example
seasonal rhinitis
Type 1 hypersensitivity
IgE mediated, binds to mast cell which causes release of histamine and other inflammatory
cytokines
Eosinphils are active in which hypersensitivity?
Type 1
Histamine binds to _ to cause allergic reaction
H1 receptors
