NUR 315 Immunity Exam Questions And Correct Answers
B lymphocytes - Answer -deals with antigens
-have Ig signaling themselves so they don't attack each other
T lymphocytes - Answer -mature strong effective T lymphocytes with the appropriate
receptors
-thymus= large @ birth, shrink with age
Lymph nodes - Answer -Vessels provide lymph -protein rich fluid
-filter material before it enters blood
Innate immunity - Answer -happening all the time
-has no memory dory
-non-specific, first line of defense
Generation of clonal diversity - Answer -how bone marrow determines what time of cells
we need based on our bodies needs
Spleen (white & red) - Answer *White pulp:* contains concentrated areas of the T and B
lymphocytes, dendritic cells
*Red pulp:* Filled with arteries and area where dead and injured blood cells are
removed
Epithelial barriers - Answer -skin, saliva, mucosa membranes, cilia, lysosomes
-first line of defense
, dendritic cell-Answer-3rd class of phagocytic cells
-adaptive role-send signals that needs more defense
-takes antigen to b & t cells
natural killer cells-Answer-innate immune system.
-first line of defense against viral infections
-cause apoptosis
"granular lymphocytes"
cytokines-Answer-stimulate neutrophils
-work on all kinds of cells
-redundant-all do the same thing
chemokines-Answer Help move T cells, B cells and dendritic cells move through the
spleen and lymph nodes
Complement system - Answer promote inflammation which destroys the microbes
From innate to adaptive - Answer 1. antigen send signal
2. innate system sends signal
3. Second signal comes from dendritic cells/macrophages and the activation of the
complement system
Antigen presenting Cells (APC) - Answer -"present" the antigen to the immune system
macrophages, B cells
Adaptive immunity - Answer -has memory
-antibodies, won't get illness again
