Micro 12 (Test 3) Flashcards
The action of the white blood cells designed to attack and destroy immunogens that enter our tissues:
cellular immunity
The physical barriers and chemicals used to prevent the entrance of microbes into the body:
non-specific immunity
The action of antibodies in the blood:
humeral immunity
TRUE or FALSE: The more toxins a bacteria can produce, the more dangerous it is to the human body
TRUE
Patrols all the tissues, particularly the skin, and knows its territory in order to attack anything that it does not recognize.
macrophages
Attacks and destroys bacteria
neutrophils
Attacks and destroys animal parasites
eosinophils/acidophils
_____ cells’ major function is to direct the attack on a any substance that gets into the tissues by releasing signal molecules.
dendritic
The signal molecules released by the dendritic cells are _____, _____, _____ and _____
cyclic adenyl monophosphate, cyclic guanosine monophosphate, hemohine, quinolone
T-Lymphocytes come in two states: _____ and ___-_____
sensitized, non-sensitized
A _____ changes the anatomy and physiology of its target cell.
hormone
_____ _____ targets other sensitized and causes the metamorphosis of 7 specialized cells.
interlukin 1
_____/_____ t-cells produce lymphotoxins/cytotoxins designed to attack and destroy the original invading bacterial population.
cytotoxic/lymphotoxic
_____ is a type of cytotoxin that destroys the cell membrane of cellular invaders.
perforin
_____ are partially digested fragments of bacteria and will undergo presentation.
epitopes
A _____ T-cell recognized the epitopes and binds to them forming an _____.
sensitized … epitome
_____ factor converts non-sensitized t-cells into sensitized t-cells.
Transfer
_____ _____ _____ factor that attracts more macrophages at the injury site.
macrophage migration chemotactic
_____ _____ _____ factor that prevents the dispersion of macrophages from injury site.
macrophage migration inhibition
_____ factor induces the replication of non-sensitized t-cells to prepare the body for future attacks.
mitagenic
_____ prevents the attachment of viruses and the replication of viruses in already infected cells.
interferon
Which type of cell emits signal molecules to macrophages telling them to attack?
Dendritic
Place in the correct order the events occuring in the cellular immunity:
a) Interleukin I is released
b) Macrophages attack the phagocitize bacteria
c) Bacteria is introduced into the body tissues
d) A sensitized t-cell recognizes the epitope and binds to it creating an epitome
e) Partially digested fragments are attached to micro tubules and pushed to the surface of the macrophage called “presentation”
C,B,E,D,A
Attacks and destroys viruses
basophils
