EXAM 4 MIC 205 DAYDIF COMPLETE
QUESTIONS AND CORRECT ANSWERS
\.specific immunity - ANSWERS✔-Third line equals, lymphocytes, antibodies,
specific immune response
Specificity - so specific, it can tell diff between E. coli, virus, mold, yeast, protozoan
A learning system - mount a response plus writes down directions on how it
mounted that response, upon a second response to same thing, it can go back to
those directions and build the same response faster + bigger
Body teaches itself differences between foreign + self
\.AB - ANSWERS✔-antibody
\.AG - ANSWERS✔-Antigen
\.Antigens - ANSWERS✔-Any molecule or piece of a molecule that triggers a
specific immune response
Fragments can be from bacteria, pollen, dirt, dust, food, anything, the immune
system, response deems as foreign
,Degree the immune response is going to be simulated will differ between
antigens.
Response = very antigenic
Poor response = less antigenic
\.How do antigens enter the body - ANSWERS✔-- Through breaks in the skin and
mucous membranes
- Direct injection, as with a bite or needle
- Through organ transplants and skin grafts
\.Epitope - ANSWERS✔-Small, accessible portion of an antigen that can be
recognized
Single molecules that illicit multiple responses from immune system
Not every single area protein stimulates its own immune response, not every area
is recognized by the immune response
Vaccines that work well have proteins that have multiple epitopes that stimulate
the immune system
\.Lymphatic system - ANSWERS✔-Network of organs, fluid - return vessels, + clean
up cells that screen the tissue of the body for foreign antigens
,\.Lymph node - ANSWERS✔-Areas were 90% of immune system takes place,
house, majority of WBC, that recognize an attack for an antigens in lymph
Concentrated and neck, groin, armpits, and abdominal regions
\.Lymphoid cells - ANSWERS✔-T cells and B cells
Includes lymphocytes, the smallest of the white blood cells; develops from stem
cells
\.Lymphatic vesicles - ANSWERS✔-one-way system of returning lymph from
lymphatic system back to circulatory system. lymph + WBC leave capillary beds
into tissue, lymph takes foreign material into lymphatic capillaries, everything
drains into lymph node where T cells, B cells, antibodies are + we feel tenderness
there, lymph nodes swell bc immune response taking place in there, lymph goes
back into circulatory system
\.Lymph - ANSWERS✔-Liquid similar to blood plasma that arises from fluid leaked
from the blood vessels into surrounding tissues
\.Tonsils + spleen - ANSWERS✔-Filter that traps foreign materials + microbes
\.Lymphocytes - ANSWERS✔-Clonal deletion
Found primarily in spleen plus lymph nodes
, Small percent circulating in blood
Activated (clonal selection) by matching single antigen, will result in cell division
Memory cell for later response
\.B cells - ANSWERS✔-Derived from stem cells, mature w/in red bone marrow
Going to be used in order to secrete antibodies
Similar when identifying self versus non-self
Come from bone marrow, go through clonal deletion, once they are screened
through clonal deletion + do not recognize self, most go to lymph nodes, small
percent go to circulatory system, then they wait for appropriate time where there
receptor is going to find the complementary antigen, then you get clonal
activation, binding takes place and cell needs to make more of itself + turn into
plasma cells to fight current antigens plus release antibodies, Also made into
memory cells to fight during a second exposure
\.T cells - ANSWERS✔-Derived from stem cells, mature, and thymus
Do not secrete antibodies
