Innate Immunity Flashcards
1
Q
megakaryocyte
A
- platelets
- activate blood clotting mechanism
2
Q
types and frequency of polymorhonuclear leukocytes
A
- neutrophils
- lymphocytes
- monocytes
- eosinophils
- basophils
Never let monkeys eat bananas
3
Q
diapedesis
A
- white blood cells can squeeze through the pores of blood capillaries even though the pore is much smaller than the cell by sliding a small portion through at a time
4
Q
chemotaxis
A
movement of white blood cells toward the source of a chemical
5
Q
hemopoetic cells
A
- cells that come from the bone marrow
- RBC
- megakaryocytes
- mononuclear phagocytic system
- polymorphonuclear leukocytes/ Gralulocytes
- lymphocytes
6
Q
monocyte
A
a mononuclear phaocyte.
same as macrophage but found in blood
7
Q
macrophage
A
- monocyte that has left blood and went into tissue
- Have three jobs
- sends message (cytokines) to alert neutrophils
- overseeing reconstruction (release growth factors)
- eating bacteria
8
Q
kupffer cell
A
macrophage in liver
9
Q
microglia
A
macrophage in brain
10
Q
dust cell
A
macrophage in lungs
11
Q
osteoclast
A
macrophage in bone
(not immune cell)
12
Q
dendritic cell
A
- mononuclear phagocyte found in peripheral tissue.
- Langerhans cell found in skin
- uptakes antigens from tissue cells and is antigen presenting cell (APC)
13
Q
Lymphocytes
A
B-cells
T-cells
NK- natural killer cells
14
Q
humoral
A
extracellular
15
Q
cell-mediated
A
intracellular
16
Q
neutrophil
A
- Lots of neutrophils, constantly circulating
- short lifespan about 4 days
- actively move themselves toward problems by chemotaxis cause by cytokines
17
Q
eosinophils
A
respond mostly to parasites/worms
18
Q
mast cells
A
respond mostly to allergens
19
Q
opsonized bacteria
A
- a bacteria with an antibody on it
- “chocolate coated”
20
Q
sinusoid
A
- part of spleen.
- RBCs have to make it through the challenge course to get to the sinusoid in order to make the cut and not get killed by macrophages chillin in the red pulp
