Inflammatory And Immune Response Quiz Flashcards
What are the main physiologic effects of stimulating histamine receptors during the inflammatory response
Vasodilation and increased capillary permeability
When histamine is released during an inflammatory response the main effects are vasodilation of the local arterioles in order to bring more WBC’s to the area and increased capillary permeability
Leukotrienes and prostaglandins play a role in
Leukotrienes and prostaglandins are synthesized by the mast cell after degranulation. The functions of these inflammatory mediators are similar to those of histamine and the mast cell will keep producing them as long as there is a stylus to do so
Ellen Harold is in a car accident and sustains a fracture to her rib cage with extensive soft tiddue injury. The pain associated with the injury is related to
Release of prostaglandins
During the inflammatory response to the infection or injury, thee primary mediators that stimulate pain are prostaglandins
The swelling of the tissue around the injury is a direct result of
Increased capillary permeability
Which circulating white blood cell is present in the greatest quantities in the blood and generally is the first to arrive at the site of an infection
Neutrophils
Eosinophils are phagocyte that play an important role in
Parasitic infection
Often times over drowned by neutrophils and phagocytes due to the low quantity
An elevation in the blood levels which of the following would indicate the presence of a chronic bone infection
Monocytes
Macrophages will be present at the site
Which of the following patients is at risk for developing infections because their levels of complaint proteins are low?
A 72 year old man with liver failure due to alcoholic cirrhosis
Compliment proteins are released by the liver
What are the primary actions/effects of activated complement proteins?
Opsonization
Vasodilation and increased cap permeability
Activated compliment have many different roles during IR.
All of the following are systematic manifestations of acute inflammation
Decreased erythrocytes sedimentation rate
Which of the following descriptions is the best definition of the term ‘antigen’ in immunology
Any molecule that is recognized by lymphocytes and reacts with antibodies
Which of the following statements about human leukocyte antigen (HLA) is true?
HLA allows the immune system to distinguish cells and bone marrow stem cells
True statements on antibodies
Antibodies are responsible for activating for clotting proteins
Antibodies are immunoglobins
Antibodies opsonization bacteria and other foreign organisms
Secretions from the mucous membranes of the respiratory and GI tracts primarily contain which of the following antibodies
IgA
Which antibody would have the highest titers during a secondary immune response
IgG
