innate immunity Correct Answer-Immunity that is present before
exposure and effective from birth. Responds to a broad range of
pathogens.
adaptive immunity Correct Answer-immunity or resistance to a specific
pathogen; slower to respond, has memory component
inflammation Correct Answer-a localized physical condition in which
part of the body becomes reddened, swollen, hot, and often painful,
especially as a reaction to injury or infection.
Cardinal signs of inflammation Correct Answer-redness, swelling, heat,
pain, loss of function
Goals of inflammation Correct Answer-Limit and control the
inflammatory process
Prevent and limit infection and further damage
Initiate adaptive immune response
Initiate healing
Degranulation Correct Answer-Release of biochemical mediators, by
mast cells, in the form of extracellular granules.
Phagocytes Correct Answer-A type of white blood cell that ingests
invading microbes; Neutrophils and Macrophages
, Neutrophils Correct Answer-A type of white blood cell that engulfs
invading microbes and contributes to the nonspecific defenses of the
body against disease.
Macrophages Correct Answer-Found within the lymph nodes, they are
phagocytes that destroy bacteria, cancer cells, and other foreign matter
in the lymphatic stream.
Leukotrienes Correct Answer-Lipids that induce smooth muscle
contraction and increased vascular permeability; Stimulate SLOWER
and more PROLONGED inflammatory responses
Histamine Correct Answer-Chemical stored in mast cells that triggers
dilation and increased vascular permeability; binds to histamine
receptors (H1 & H2); causes RAPID contraction of smooth muscle
Prostaglandins Correct Answer-Modified fatty acids that are produced
by a wide range of cells; cause increased vascular permeability,
neutrophil chemotaxis, and pain
clotting cascade Correct Answer-1)Platelet finds exposed collagen of
damaged vessel 2) Platelet releases chemical that causes neighboring
platelets to adhere to each other (platelet plug) 3)collected platelets and
damaged tissue both released thromboplastin
4) Thromboplastin and calcium and vit.K converts inactive prothrombin
to its active form thrombin
