PAT 201 EXAM 3 QUESTIONS AND 100%
CORECT ANSWERS!!
What is the function of an integrin on a leukocyte?
normally inactive, found on leukocytes. Sprout when L-selectin CAMs sprout from endothelial
cells. Helps leukocytes adhere to endothelial cells. Part of inflammation
what is innate/natural/native immunity?
natural epithelial barrier nd inflammation
What is adaptive immunity?
the body's ability to recognize and defend itself against distinct invaders and their products;
relatively, slow to develop, more rapidly targets and eradicates a second infection with a
particular disease-causing microorg
Which type of innate immunity has memory?
3rd line
adaptive/acquired immunity
has specific immunologic memory by T and B lymphocytes
What is a cytokine?
Broad and loose category of small proteins important in cell signally
produced by several immune cells and essential to inflammation
What is the main function of histamines?
functions in allergic reactions, inflammtino
What is the function of bradykinin?
The primary component in kinin system
, causes dilation of blood vessels, pain, smooth muscle contraction, vascular permeability, and
leukocyte chemotaxis
Define chemotaxis
chemo: r/t chemical actions or chemicals
taxis: "arrangement
it is the migration of cells in response to concentration gradients of extracellular signals
What is a leukotriene?
one of two pathways in arachidonic pathway (the other is cyclooxygenase pathway)
creates smooth muscle contraction, bronchoconstriction, vasoconstriction, vascular permeability
similar to histamine, more important in later stage of inflammation
What is a prostaglandin?
Similar effects to leukotrienes, induce pain
One of two pathways in arachidonic pathway (other is leukotriene pathway)
Made from cyclooxygenase 1 & 2
Maintains organ function, protects gastric mucosa, mediates pain & inflammation,
vasodilation/vasoconstriction, bronchoconstriction, platelet function
What is a proenzyme?
Pro- greek for "before"
inactive enzymes that circulate in the body; r/t plasma protein systems of inflammation
Name the 3 plasma protein systems (inflammation)
